Struct rug::Float

pub struct Float { /* fields omitted */ }

A multi-precision floating-point number with arbitrarily large precision and correct rounding

The precision has to be set during construction. The rounding method of the required operations can be specified, and the direction of the rounding is returned.

Examples

use rug::Float;
use rug::float::Round;
use rug::ops::DivAssignRound;
use std::cmp::Ordering;
// A precision of 32 significant bits is specified here.
// (The primitive `f32` has a precision of 24 and
// `f64` has a precision of 53.)
let mut two_thirds_down = Float::with_val(32, 2.0);
let dir = two_thirds_down.div_assign_round(3.0, Round::Down);
// since we rounded down, direction is Ordering::Less
assert_eq!(dir, Ordering::Less);
let mut two_thirds_up = Float::with_val(32, 2.0);
let dir = two_thirds_up.div_assign_round(3.0, Round::Up);
// since we rounded up, direction is Ordering::Greater
assert_eq!(dir, Ordering::Greater);
let diff_expected = 2.0_f64.powi(-32);
let diff = two_thirds_up - two_thirds_down;
assert_eq!(diff, diff_expected);

Operations on two borrowed Float numbers result in an incomplete-computation value that has to be assigned to a new Float value.

use rug::Float;
let a = Float::with_val(53, 10.5);
let b = Float::with_val(53, -1.25);
let a_b_ref = &a + &b;
let a_b = Float::with_val(53, a_b_ref);
assert_eq!(a_b, 9.25);

As a special case, when an incomplete-computation value is obtained from multiplying two Float references, it can be added to or subtracted from another Float (or reference). This will result in a fused multiply-accumulate operation, with only one rounding operation taking place.

use rug::Float;
// Use only 4 bits of precision for demonstration purposes.
// 24 in binary is 11000.
let a = Float::with_val(4, 24);
// 1.5 in binary is 1.1.
let mul1 = Float::with_val(4, 1.5);
// -13 in binary is -1101.
let mul2 = Float::with_val(4, -13);
// 24 + 1.5 * -13 = 4.5
let add = Float::with_val(4, &a + &mul1 * &mul2);
assert_eq!(add, 4.5);
// 24 - 1.5 * -13 = 43.5, rounded to 44 using four bits of precision.
let sub = a - &mul1 * &mul2;
assert_eq!(sub, 44);

// With separate addition and multiplication:
let a = Float::with_val(4, 24);
// No borrows, so multiplication is computed immediately.
// 1.5 * -13 = -19.5 (binary -10011.1), rounded to -20.
let separate_add = a + mul1 * mul2;
assert_eq!(separate_add, 4);

The incomplete-computation value obtained from multiplying two Float references can also be added to or subtracted from another such incomplete-computation value, so that two muliplications and an addition are fused with only one rounding operation taking place.

use rug::Float;
let a = Float::with_val(53, 24);
let b = Float::with_val(53, 1.5);
let c = Float::with_val(53, 12);
let d = Float::with_val(53, 2);
// 24 * 1.5 + 12 * 2 = 60
let add = Float::with_val(53, &a * &b + &c * &d);
assert_eq!(add, 60);
// 24 * 1.5 - 12 * 2 = 12
let sub = Float::with_val(53, &a * &b - &c * &d);
assert_eq!(sub, 12);

The Float type supports various functions. Most methods have four versions:

1. The first method consumes the operand and rounds the returned Float to the nearest representable value.
2. The second method has a “_mut” suffix, mutates the operand and rounds it the nearest representable value.
3. The third method has a “_round” suffix, mutates the operand, applies the specified rounding method, and returns the rounding direction:
   • Ordering::Less if the stored value is less than the exact result,
   • Ordering::Equal if the stored value is equal to the exact result,
   • Ordering::Greater if the stored value is greater than the exact result.
4. The fourth method has a “_ref” suffix and borrows the operand. The returned item is an incomplete-computation value that can be assigned to a Float; the rounding method is selected during the assignment.

use rug::Float;
use rug::float::Round;
use std::cmp::Ordering;
let expected = 0.9490_f64;

// 1. consume the operand, round to nearest
let a = Float::with_val(53, 1.25);
let sin_a = a.sin();
assert!((sin_a - expected).abs() < 0.0001);

// 2. mutate the operand, round to nearest
let mut b = Float::with_val(53, 1.25);
b.sin_mut();
assert!((b - expected).abs() < 0.0001);

// 3. mutate the operand, apply specified rounding
let mut c = Float::with_val(4, 1.25);
// using 4 significant bits, 0.9490 is rounded down to 0.9375
let dir = c.sin_round(Round::Nearest);
assert_eq!(c, 0.9375);
assert_eq!(dir, Ordering::Less);

// 4. borrow the operand
let d = Float::with_val(53, 1.25);
let r = d.sin_ref();
let sin_d = Float::with_val(53, r);
assert!((sin_d - expected).abs() < 0.0001);
// d was not consumed
assert_eq!(d, 1.25);

pub fn parse<S: AsRef<[u8]>>(src: S) -> Result<ParseIncomplete, ParseFloatError>

Parses a decimal string slice (&str) or byte slice (&[u8]) into a Float.

AssignRound<Src> for Float is implemented with the unwrapped returned incomplete-computation value as Src.

The string can start with an optional minus or plus sign and must then have one or more significant digits with an optional decimal point. This can optionally be followed by an exponent; the exponent can start with a separator ‘e’, ‘E’ or ‘@’, and is followed by an optional minus or plus sign and by one or more decimal digits.

Alternatively, the string can indicate the special values infinity or NaN. Infinity can be represented as "inf", "infinity", "@inf@" or "@infinity@",and NaN can be represented as "nan" or "@nan@". All of these special representations are case insensitive. The NaN representation may also include a possibly-empty string of ASCII letters, digits and underscores enclosed in brackets, for example "nan(char_sequence_1)".

ASCII whitespace is ignored everywhere in the string except in the substrings specified above for special values; for example " @inf@ " is accepted but "@ inf @" is not. Underscores are ignored anywhere in digit strings except before the first digit and between the exponent separator and the first digit of the exponent.

Examples

use rug::Float;

let valid = Float::parse("12.25e-4");
let f = Float::with_val(53, valid.unwrap());
assert_eq!(f, 12.25e-4);

let invalid = Float::parse(".e-4");
assert!(invalid.is_err());

pub fn parse_radix<S: AsRef<[u8]>>(
    src: S,
    radix: i32
) -> Result<ParseIncomplete, ParseFloatError>

Parses a string slice (&str) or byte slice (&[u8]) into a Float.

AssignRound<Src> for Float is implemented with the unwrapped returned incomplete-computation value as Src.

The string can start with an optional minus or plus sign and must then have one or more significant digits with an optional point. This can optionally be followed by an exponent; the exponent can start with a separator ‘e’ or ‘E’ if the radix ≤ 10, or ‘@’ for any radix, and is followed by an optional minus or plus sign and by one or more decimal digits.

Alternatively, the string can indicate the special values infinity or NaN. If the radix ≤ 10, infinity can be represented as "inf" or "infinity", and NaN can be represented as "nan". For any radix, infinity can also be represented as "@inf@" or "@infinity@", and NaN can be represented as "@nan@". All of these special representations are case insensitive. The NaN representation may also include a possibly-empty string of ASCII letters, digits and underscores enclosed in brackets, for example "nan(char_sequence_1)".

ASCII whitespace is ignored everywhere in the string except in the substrings specified above for special values; for example " @inf@ " is accepted but "@ inf @" is not. Underscores are ignored anywhere in digit strings except before the first digit and between the exponent separator and the first digit of the exponent.

Panics

Panics if radix is less than 2 or greater than 36.

Examples

use rug::Float;

let valid1 = Float::parse_radix("12.23e-4", 4);
let f1 = Float::with_val(53, valid1.unwrap());
assert_eq!(f1, (2.0 + 4.0 * 1.0 + 0.25 * (2.0 + 0.25 * 3.0)) / 256.0);
let valid2 = Float::parse_radix("12.yz@2", 36);
let f2 = Float::with_val(53, valid2.unwrap());
assert_eq!(f2, 35 + 36 * (34 + 36 * (2 + 36 * 1)));

let invalid = Float::parse_radix("ffe-2", 16);
assert!(invalid.is_err());

pub fn to_integer(&self) -> Option<Integer>

If the value is a finite number, converts it to an Integer rounding to the nearest.

Examples

use rug::Float;
let f = Float::with_val(53, 13.7);
let i = match f.to_integer() {
    Some(i) => i,
    None => unreachable!(),
};
assert_eq!(i, 14);

pub fn to_integer_round(&self, round: Round) -> Option<(Integer, Ordering)>

Examples

use rug::Float;
use rug::float::Round;
use std::cmp::Ordering;
let f = Float::with_val(53, 13.7);
let (i, dir) = match f.to_integer_round(Round::Down) {
    Some(i_dir) => i_dir,
    None => unreachable!(),
};
assert_eq!(i, 13);
assert_eq!(dir, Ordering::Less);

pub fn to_integer_exp(&self) -> Option<(Integer, i32)>

If the value is a finite number, returns an Integer and exponent such that it is exactly equal to the integer multiplied by two raised to the power of the exponent.

Examples

use rug::{Assign, Float};
use rug::float::Special;
let mut float = Float::with_val(16, 6.5);
// 6.5 in binary is 110.1
// Since the precision is 16 bits, this becomes
// 1101_0000_0000_0000 times two to the power of -12
let (int, exp) = float.to_integer_exp().unwrap();
assert_eq!(int, 0b1101_0000_0000_0000);
assert_eq!(exp, -13);

float.assign(0);
let (zero, _) = float.to_integer_exp().unwrap();
assert_eq!(zero, 0);

float.assign(Special::Infinity);
assert!(float.to_integer_exp().is_none());

pub fn to_rational(&self) -> Option<Rational>

If the value is a finite number, returns a Rational number preserving all the precision of the value.

If the compiler supports TryFrom, this conversion can also be performed using Rational::try_from(&float) or Rational::try_from(float).

Examples

use rug::{Float, Rational};
use rug::float::Round;
use std::str::FromStr;
use std::cmp::Ordering;

// Consider the number 123,456,789 / 10,000,000,000.
let parse = Float::parse("0.0123456789").unwrap();
let (f, f_rounding) = Float::with_val_round(35, parse, Round::Down);
assert_eq!(f_rounding, Ordering::Less);
let r = Rational::from_str("123456789/10000000000").unwrap();
// Set fr to the value of f exactly.
let fr = f.to_rational().unwrap();
// Since f == fr and f was rounded down, r != fr.
assert_ne!(r, fr);
let (frf, frf_rounding) = Float::with_val_round(35, &fr, Round::Down);
assert_eq!(frf_rounding, Ordering::Equal);
assert_eq!(frf, f);
assert_eq!(format!("{:.9}", frf), "1.23456789e-2");

In the following example, the Float values can be represented exactly.

use rug::Float;

let large_f = Float::with_val(16, 6.5);
let large_r = large_f.to_rational().unwrap();
let small_f = Float::with_val(16, -0.125);
let small_r = small_f.to_rational().unwrap();

assert_eq!(*large_r.numer(), 13);
assert_eq!(*large_r.denom(), 2);
assert_eq!(*small_r.numer(), -1);
assert_eq!(*small_r.denom(), 8);

pub fn to_i32_saturating(&self) -> Option<i32>

• The gmp_mpfr_sys::mpfr::mpfr_t type can be considered as a kind of pointer, so there can be multiple copies of it. Since this function takes over ownership, no other copies of the passed value should exist.

Examples

extern crate gmp_mpfr_sys;
extern crate rug;
use gmp_mpfr_sys::mpfr;
use rug::Float;
use std::mem;
fn main() {
    let f = unsafe {
        let mut m = mem::uninitialized();
        mpfr::init2(&mut m, 53);
        mpfr::set_d(&mut m, -14.5, mpfr::rnd_t::RNDN);
        // m is initialized and unique
        Float::from_raw(m)
    };
    assert_eq!(f, -14.5);
    // since f is a Float now, deallocation is automatic
}

pub fn into_raw(self) -> mpfr_t

Converts a Float into an MPFR floating-point number.

The returned object should be freed to avoid memory leaks.

Examples

extern crate gmp_mpfr_sys;
extern crate rug;
use gmp_mpfr_sys::mpfr;
use rug::Float;
fn main() {
    let f = Float::with_val(53, -14.5);
    let mut m = f.into_raw();
    unsafe {
        let d = mpfr::get_d(&m, mpfr::rnd_t::RNDN);
        assert_eq!(d, -14.5);
        // free object to prevent memory leak
        mpfr::clear(&mut m);
    }
}

pub fn as_raw(&self) -> *const mpfr_t

Returns a pointer to the inner MPFR floating-point number.

The returned pointer will be valid for as long as self is valid.

Examples

extern crate gmp_mpfr_sys;
extern crate rug;
use gmp_mpfr_sys::mpfr;
use rug::Float;
fn main() {
    let f = Float::with_val(53, -14.5);
    let m_ptr = f.as_raw();
    unsafe {
        let d = mpfr::get_d(m_ptr, mpfr::rnd_t::RNDN);
        assert_eq!(d, -14.5);
    }
    // f is still valid
    assert_eq!(f, -14.5);
}

pub fn as_raw_mut(&mut self) -> *mut mpfr_t

Returns an unsafe mutable pointer to the inner MPFR floating-point number.

The returned pointer will be valid for as long as self is valid.

Examples

extern crate gmp_mpfr_sys;
extern crate rug;
use gmp_mpfr_sys::mpfr;
use rug::Float;
fn main() {
    let mut f = Float::with_val(53, -14.5);
    let m_ptr = f.as_raw_mut();
    unsafe {
        mpfr::add_ui(m_ptr, m_ptr, 10, mpfr::rnd_t::RNDN);
    }
    assert_eq!(f, -4.5);
}

pub fn as_neg(&self) -> BorrowFloat

Borrows a negated copy of the Float.

The returned object implements Deref<Target = Float>.

This method performs a shallow copy and negates it, and negation does not change the allocated data.

Examples

use rug::Float;
let f = Float::with_val(53, 4.2);
let neg_f = f.as_neg();
assert_eq!(*neg_f, -4.2);
// methods taking &self can be used on the returned object
let reneg_f = neg_f.as_neg();
assert_eq!(*reneg_f, 4.2);
assert_eq!(*reneg_f, f);

pub fn as_abs(&self) -> BorrowFloat

Borrows an absolute copy of the Float.

The returned object implements Deref<Target = Float>.

This method performs a shallow copy and possibly negates it, and negation does not change the allocated data.

Examples

use rug::Float;
let f = Float::with_val(53, -4.2);
let abs_f = f.as_abs();
assert_eq!(*abs_f, 4.2);
// methods taking &self can be used on the returned object
let reabs_f = abs_f.as_abs();
assert_eq!(*reabs_f, 4.2);
assert_eq!(*reabs_f, *abs_f);

pub fn as_ord(&self) -> &OrdFloat

let nan = nan_f.as_ord();
assert_eq!(nan.cmp(nan), Ordering::Equal);

let neg_inf_f = Float::with_val(53, Special::NegInfinity);
let neg_inf = neg_inf_f.as_ord();
assert_eq!(nan.cmp(neg_inf), Ordering::Less);

let zero_f = Float::with_val(53, Special::Zero);
let zero = zero_f.as_ord();

assert!(f.is_integer());

pub fn is_nan(&self) -> bool

Returns true if self is not a number.

assert!(!f.is_finite());

pub fn is_zero(&self) -> bool

Returns true if self is plus or minus zero.

Examples

use rug::{Assign, Float};
use rug::float::Special;
let mut f = Float::with_val(53, Special::Zero);
assert!(f.is_zero());
f.assign(Special::NegZero);
assert!(f.is_zero());
f += 1;
assert!(!f.is_zero());

pub fn is_normal(&self) -> bool

Returns true if self is a normal number, that is neither NaN, nor infinity, nor zero. Note that Float cannot be subnormal.

Examples

use rug::{Assign, Float};
use rug::float::Special;
let mut f = Float::with_val(53, Special::Zero);
assert!(!f.is_normal());
f += 5.2;
assert!(f.is_normal());
f.assign(Special::Infinity);
assert!(!f.is_normal());
f.assign(Special::Nan);
assert!(!f.is_normal());

pub fn classify(&self) -> FpCategory

use rug::float::Special;
use std::num::FpCategory;
let nan = Float::with_val(53, Special::Nan);
let infinite = Float::with_val(53, Special::Infinity);

let normal = Float::with_val(53, 2.3);
assert_eq!(nan.classify(), FpCategory::Nan);
assert_eq!(infinite.classify(), FpCategory::Infinite);
assert_eq!(zero.classify(), FpCategory::Zero);
assert_eq!(normal.classify(), FpCategory::Normal);

pub fn cmp0(&self) -> Option<Ordering>

Returns the same result as self.partial_cmp(&0), but is faster.

Examples

use rug::{Assign, Float};
use rug::float::Special;
use std::cmp::Ordering;
let mut f = Float::with_val(53, Special::NegZero);
assert_eq!(f.cmp0(), Some(Ordering::Equal));
f += 5.2;
assert_eq!(f.cmp0(), Some(Ordering::Greater));
f.assign(Special::NegInfinity);
assert_eq!(f.cmp0(), Some(Ordering::Less));
f.assign(Special::Nan);
assert_eq!(f.cmp0(), None);

pub fn cmp_abs(&self, other: &Self) -> Option<Ordering>

Compares the absolute values of self and other.

Examples

use rug::Float;
use std::cmp::Ordering;
let a = Float::with_val(53, -10);
let b = Float::with_val(53, 4);
assert_eq!(a.partial_cmp(&b), Some(Ordering::Less));
assert_eq!(a.cmp_abs(&b), Some(Ordering::Greater));

pub fn get_exp(&self) -> Option<i32>

If the value is a normal number, returns its exponent.

The significand is assumed to be in the range 0.5 ≤ x < 1.

Examples

use rug::{Assign, Float};
// -(2.0 ^ 32) == -(0.5 * 2 ^ 33)
let mut f = Float::with_val(53, -32f64.exp2());
assert_eq!(f.get_exp(), Some(33));
// 0.8 * 2 ^ -39
f.assign(0.8 * (-39f64).exp2());
assert_eq!(f.get_exp(), Some(-39));
f.assign(0);
assert_eq!(f.get_exp(), None);

pub fn get_significand(&self) -> Option<BorrowInteger>

If the value is a normal number, returns a reference to its significand as an Integer.

The unwrapped returned object implements Deref<Target = Integer>.

The number of significant bits of a returned significand is at least equal to the precision, but can be larger. It is usually rounded up to a multiple of 32 or 64 depending on the implementation; in this case, the extra least significant bits will be zero. The value of self is exactly equal to the returned Integer divided by two raised to the power of the number of significant bits and multiplied by two raised to the power of the exponent of self.

Unlike the to_integer_exp method which returns an owned Integer, this method only performs a shallow copy and does not allocate any memory.

Examples

use rug::Float;
let float = Float::with_val(16, 6.5);
// 6.5 in binary is 110.1 = 0.1101 times two to the power of 3
let exp = float.get_exp().unwrap();
assert_eq!(exp, 3);
let significand = float.get_significand().unwrap();
let sig_bits = significand.significant_bits();
// sig_bits must be greater or equal to precision
assert!(sig_bits >= 16);
let (check_int, check_exp) = float.to_integer_exp().unwrap();
assert_eq!(check_int << sig_bits << (check_exp - exp), *significand);

pub fn is_sign_positive(&self) -> bool

Returns true if the value is positive, +0 or NaN without a negative sign.

Examples

use rug::Float;
let pos = Float::with_val(53, 1.0);
let neg = Float::with_val(53, -1.0);
assert!(pos.is_sign_positive());
assert!(!neg.is_sign_positive());

pub fn is_sign_negative(&self) -> bool

Returns true if the value is negative, −0 or NaN with a negative sign.

Examples

use rug::Float;
let neg = Float::with_val(53, -1.0);
let pos = Float::with_val(53, 1.0);
assert!(neg.is_sign_negative());
assert!(!pos.is_sign_negative());

pub fn next_toward(&mut self, to: &Self)

Sets to the next value towards to.

Examples

use rug::Float;
let to = Float::with_val(8, 100);
// 32.5 in binary is 100000.10
// 32.75 in binary is 100000.11
let mut f = Float::with_val(8, 32.5);
f.next_toward(&to);
assert_eq!(f, 32.75);

pub fn next_up(&mut self)

Sets to the next value towards +∞.

Examples

use rug::Float;
// 32.5 in binary is 100000.10
// 32.75 in binary is 100000.11
let mut f = Float::with_val(8, 32.5);
f.next_up();
assert_eq!(f, 32.75);

pub fn next_down(&mut self)

Sets to the next value towards −∞.

Examples

use rug::Float;
// 32.5 in binary is 100000.10
// 32.25 in binary is 100000.01
let mut f = Float::with_val(8, 32.5);
f.next_down();
assert_eq!(f, 32.25);

pub fn subnormalize_ieee(&mut self) -> &mut Self

Emulate subnormal numbers for precisions specified in IEEE 754, rounding to the nearest.

Subnormalization is only performed for precisions specified in IEEE 754:

• binary16 with 16 storage bits and a precision of 11 bits,
• binary32 (single precision) with 32 storage bits and a precision of 24 bits,
• binary64 (double precision) with 64 storage bits and a precision of 53 bits,
• binary{k} with k storage bits where k is a multiple of 32 and k ≥ 128, and a precision of k − round(4 × log₂ k) + 13 bits.

This method has no effect if the value is not in the subnormal range.

Examples

use rug::Float;
use std::f32;
// minimum single subnormal is 0.5 * 2 ^ -148 = 2 ^ -149
let single_min_subnormal = (-149f64).exp2();
assert_eq!(single_min_subnormal, single_min_subnormal as f32 as f64);
let single_cannot = single_min_subnormal * 1.25;
assert_eq!(single_min_subnormal, single_cannot as f32 as f64);
let mut f = Float::with_val(24, single_cannot);
assert_eq!(f.to_f64(), single_cannot);
f.subnormalize_ieee();
assert_eq!(f.to_f64(), single_min_subnormal);

pub fn subnormalize_ieee_round(
    &mut self,
    prev_rounding: Ordering,
    round: Round
) -> Ordering

Emulate subnormal numbers for precisions specified in IEEE 754, applying the specified rounding method.

Subnormalization is only performed for precisions specified in IEEE 754:

• binary16 with 16 storage bits and a precision of 11 bits,
• binary32 (single precision) with 32 storage bits and a precision of 24 bits,
• binary64 (double precision) with 64 storage bits and a precision of 53 bits,
• binary{k} with k storage bits where k is a multiple of 32 and k ≥ 128, and a precision of k − round(4 × log₂ k) + 13 bits.

This method simply propagates prev_rounding if the value is not in the subnormal range.

Examples

use rug::Float;
use rug::float::Round;
use std::cmp::Ordering;
use std::f32;
// minimum single subnormal is 0.5 * 2 ^ -148 = 2 ^ -149
let single_min_subnormal = (-149f64).exp2();
assert_eq!(single_min_subnormal, single_min_subnormal as f32 as f64);
let single_cannot = single_min_subnormal * 1.25;
assert_eq!(single_min_subnormal, single_cannot as f32 as f64);
let mut f = Float::with_val(24, single_cannot);
assert_eq!(f.to_f64(), single_cannot);
let dir = f.subnormalize_ieee_round(Ordering::Equal, Round::Up);
assert_eq!(f.to_f64(), single_min_subnormal * 2.0);
assert_eq!(dir, Ordering::Greater);

pub fn subnormalize(&mut self, normal_exp_min: i32) -> &mut Self

Emulate subnormal numbers, rounding to the nearest.

Subnormalization is only performed when the exponent lies within the subnormal range, that is when normal_exp_min − precision + 1 ≤ exponent < normal_exp_min. For example, for IEEE 754 single precision, the precision is 24 and normal_exp_min is −125, so the subnormal range would be −148 ≤ exponent < −125.

This method has no effect if the value is not in the subnormal range.

Examples

use rug::Float;
use std::f32;
// minimum single subnormal is 0.5 * 2 ^ -148 = 2 ^ -149
let single_min_subnormal = (-149f64).exp2();
assert_eq!(single_min_subnormal, single_min_subnormal as f32 as f64);
let single_cannot = single_min_subnormal * 1.25;
assert_eq!(single_min_subnormal, single_cannot as f32 as f64);
let mut f = Float::with_val(24, single_cannot);
assert_eq!(f.to_f64(), single_cannot);
f.subnormalize(-125);
assert_eq!(f.to_f64(), single_min_subnormal);

pub fn subnormalize_round(
    &mut self,
    normal_exp_min: i32,
    prev_rounding: Ordering,
    round: Round
) -> Ordering

Emulate subnormal numbers, applying the specified rounding method.

Subnormalization is only performed when the exponent lies within the subnormal range, that is when normal_exp_min − precision + 1 ≤ exponent < normal_exp_min. For example, for IEEE 754 single precision, the precision is 24 and normal_exp_min is −125, so the subnormal range would be −148 ≤ exponent < −125.

This method simply propagates prev_rounding if the value is not in the subnormal range.

Examples

use rug::Float;
use rug::float::Round;
use std::cmp::Ordering;
use std::f32;
// minimum single subnormal is 0.5 * 2 ^ -148 = 2 ^ -149
let single_min_subnormal = (-149f64).exp2();
assert_eq!(single_min_subnormal, single_min_subnormal as f32 as f64);
let single_cannot = single_min_subnormal * 1.25;
assert_eq!(single_min_subnormal, single_cannot as f32 as f64);
let mut f = Float::with_val(24, single_cannot);
assert_eq!(f.to_f64(), single_cannot);
let dir = f.subnormalize_round(-125, Ordering::Equal, Round::Up);
assert_eq!(f.to_f64(), single_min_subnormal * 2.0);
assert_eq!(dir, Ordering::Greater);

// The result should still be exact if it fits.
let r = Float::sum(values.iter());
let sum = Float::with_val(4, r);
assert_eq!(sum, 0.5);

let mut f = Float::with_val(4, 15.0);
// 15.5 using 4 bits of precision becomes 16.0
let r = Float::sum(values.iter());
let dir = f.add_assign_round(r, Round::Nearest);
assert_eq!(f, 16.0);
assert_eq!(dir, Ordering::Greater);

pub fn mul_add(self, mul: &Self, add: &Self) -> Self

pub fn trunc_fract(self, fract: Self) -> (Self, Self)

Gets the integer and fractional parts of the number, rounding to the nearest.

The integer part is stored in self and keeps its precision, while the fractional part is stored in fract keeping its precision.

Examples

use rug::Float;
let f1 = Float::with_val(53, -23.75);
let (trunc1, fract1) = f1.trunc_fract(Float::new(53));
assert_eq!(trunc1, -23);

let f2 = Float::with_val(53, 23.75);
let (trunc2, fract2) = f2.trunc_fract(Float::new(53));
assert_eq!(trunc2, 23);
assert_eq!(fract2, 0.75);

pub fn trunc_fract_mut(&mut self, fract: &mut Self)

Gets the integer and fractional parts of the number, rounding to the nearest.

The integer part is stored in self and keeps its precision, while the fractional part is stored in fract keeping its precision.

Examples

use rug::Float;
let mut f1 = Float::with_val(53, -23.75);
let mut fract1 = Float::new(53);
f1.trunc_fract_mut(&mut fract1);
assert_eq!(f1, -23);
assert_eq!(fract1, -0.75);
let mut f2 = Float::with_val(53, 23.75);
let mut fract2 = Float::new(53);

assert_eq!(fract2, 0.75);

pub fn trunc_fract_round(
    &mut self,
    fract: &mut Self,
    round: Round
) -> (Ordering, Ordering)

Gets the integer and fractional parts of the number, applying the specified rounding method.

The first element of the returned tuple of rounding directions is always Ordering::Equal, as truncating a value in place will always be exact.

The integer part is stored in self and keeps its precision, while the fractional part is stored in fract keeping its precision.

Examples

use rug::Float;
use rug::float::Round;
use std::cmp::Ordering;
// 0.515625 in binary is 0.100001
let mut f1 = Float::with_val(53, -23.515625);
let mut fract1 = Float::new(4);
let dir1 = f1.trunc_fract_round(&mut fract1, Round::Nearest);
assert_eq!(f1, -23);
assert_eq!(fract1, -0.5);
assert_eq!(dir1, (Ordering::Equal, Ordering::Greater));
let mut f2 = Float::with_val(53, 23.515625);
let mut fract2 = Float::new(4);
let dir2 = f2.trunc_fract_round(&mut fract2, Round::Nearest);
assert_eq!(f2, 23);
assert_eq!(fract2, 0.5);
assert_eq!(dir2, (Ordering::Equal, Ordering::Less));

pub fn trunc_fract_ref(&self) -> TruncFractIncomplete

Gets the integer and fractional parts of the number.

Assign<Src> for Float and AssignRound<Src> for Float are implemented with the returned incomplete-computation value as Src.

Examples

use rug::{Assign, Float};
let f1 = Float::with_val(53, -23.75);
let r1 = f1.trunc_fract_ref();
let (mut trunc1, mut fract1) = (Float::new(53), Float::new(53));
(&mut trunc1, &mut fract1).assign(r1);
assert_eq!(trunc1, -23);
assert_eq!(fract1, -0.75);
let f2 = Float::with_val(53, -23.75);
let r2 = f2.trunc_fract_ref();
let (mut trunc2, mut fract2) = (Float::new(53), Float::new(53));

assert_eq!(trunc2, -23);
assert_eq!(fract2, -0.75);

pub fn random_bits<'a, 'b: 'a>(
    rng: &'a mut RandState<'b>
) -> RandomBitsIncomplete<'a, 'b>

Generates a random number in the range 0 ≤ x < 1.

This is equivalent to generating a random integer in the range 0 ≤ x < 2^p, where 2^p is two raised to the power of the precision, and then dividing the integer by 2^p. The smallest non-zero result will thus be 2^−p, and will only have one bit set. In the smaller possible results, many bits will be zero, and not all the precision will be used.

There is a corner case where the generated random number is converted to NaN: if the precision is very large, the generated random number could have an exponent less than the allowed minimum exponent, and NaN is used to indicate this. For this to occur in practice, the minimum exponent has to be set to have a very small magnitude using the low-level MPFR interface, or the random number generator has to be designed specifically to trigger this case.

Assign<Src> for Float is implemented with the returned incomplete-computation value as Src.

Examples

use rug::{Assign, Float};
use rug::rand::RandState;
let mut rand = RandState::new();
let mut f = Float::new(2);
f.assign(Float::random_bits(&mut rand));
assert!(f == 0.0 || f == 0.25 || f == 0.5 || f == 0.75);
println!("0.0 ≤ {} < 1.0", f);

pub fn random_cont<'a, 'b: 'a>(rng: &'a mut RandState<'b>) -> RandomCont<'a, 'b>

Generates a random number in the continuous range 0 ≤ x < 1.

The result can be rounded up to be equal to one. Unlike the random_bits method which generates a discrete random number at intervals depending on the precision, this method is equivalent to generating a continuous random number with infinite precision and then rounding the result. This means that even the smaller numbers will be using all the available precision bits, and rounding is performed in all cases, not in some corner case.

Rounding directions for generated random numbers cannot be Ordering::Equal, as the random numbers generated can be considered to have infinite precision before rounding.

Assign<Src> for Float and [AssignRound<Src> for Float][AssignRound] are implemented with the returned incomplete-computation value as Src.

Examples

use rug::Float;
use rug::rand::RandState;
let mut rand = RandState::new();
let f = Float::with_val(2, Float::random_cont(&mut rand));
// The significand is either 0b10 or 0b11
assert!(
    f == 1.0 || f == 0.75 || f == 0.5 || f == 0.375
        || f == 0.25 || f <= 0.1875
);

pub fn random_normal<'a, 'b: 'a>(
    rng: &'a mut RandState<'b>
) -> RandomNormal<'a, 'b>

Generates a random number according to a standard normal Gaussian distribution, rounding to the nearest.

Rounding directions for generated random numbers cannot be Ordering::Equal, as the random numbers generated can be considered to have infinite precision before rounding.

Assign<Src> for Float and AssignRound<Src> for Float are implemented with the returned incomplete-computation value as Src.

Examples

use rug::Float;
use rug::rand::RandState;
let mut rand = RandState::new();
let f = Float::with_val(53, Float::random_normal(&mut rand));
println!("Normal random number: {}", f);

pub fn random_exp<'a, 'b: 'a>(rng: &'a mut RandState<'b>) -> RandomExp<'a, 'b>

Generates a random number according to an exponential distribution with mean one, rounding to the nearest.

Rounding directions for generated random numbers cannot be Ordering::Equal, as the random numbers generated can be considered to have infinite precision before rounding.

Assign<Src> for Float and AssignRound<Src> for Float are implemented with the returned incomplete-computation value as Src.
