Struct rug::complex::SmallComplex [−] [src]

#[repr(C)]
pub struct SmallComplex { /* fields omitted */ }

A small complex number that does not require any memory allocation.

This can be useful when you have real and imaginary numbers that are primitive integers or floats and you need a reference to a Complex.

The SmallComplex will have a precision according to the types of the primitives used to set its real and imaginary parts. Note that if different types are used to set the parts, the parts can have different precisions.

i8, u8: the part will have eight bits of precision.
i16, u16: the part will have 16 bits of precision.
i32, u32: the part will have 32 bits of precision.
i64, u64: the part will have 64 bits of precision.
i128, u128: (if supported by the compiler) the SmallFloat will have 128 bits of precision.
isize, usize: the part will have 32 or 64 bits of precision, depending on the platform.
f32: the part will have 24 bits of precision.
f64: the part will have 53 bits of precision.

The SmallComplex type can be coerced to a Complex, as it implements Deref<Target = Complex>.

Examples

use rug::Complex;
use rug::complex::SmallComplex;
// `a` requires a heap allocation
let mut a = Complex::with_val(53, (1, 2));
// `b` can reside on the stack
let b = SmallComplex::from((-10f64, -20.5f64));
a += &*b;
assert_eq!(*a.real(), -9);
assert_eq!(*a.imag(), -18.5);

Methods

`impl SmallComplex`
[src]

`pub unsafe fn as_nonreallocating_complex(&mut self) -> &mut Complex`
[src]

Returns a mutable reference to a Complex number for simple operations that do not need to change the precision of the real or imaginary part.

Safety

It is undefined behaviour to modify the precision of the referenced Complex number or to swap it with another number.

Examples

use rug::complex::SmallComplex;
let mut c = SmallComplex::from((1.0f32, 3.0f32));
// rotation does not change the precision
unsafe {
    c.as_nonreallocating_complex().mul_i_mut(false);
}
assert_eq!(*c, (-3.0, 1.0));

Methods from Deref<Target = Complex>

`pub fn prec(&self) -> (u32, u32)`
[src]

Returns the precision of the real and imaginary parts.

Examples

use rug::Complex;
let r = Complex::new((24, 53));
assert_eq!(r.prec(), (24, 53));

`pub fn to_string_radix(&self, radix: i32, num_digits: Option<usize>) -> String`
[src]

Returns a string representation of the value for the specified radix rounding to the nearest.

The exponent is encoded in decimal. If the number of digits is not specified, the output string will have enough precision such that reading it again will give the exact same number.

Panics

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

Examples

use rug::Complex;
let c1 = Complex::with_val(53, 0);
assert_eq!(c1.to_string_radix(10, None), "(0.0 0.0)");
let c2 = Complex::with_val(12, (15, 5));
assert_eq!(c2.to_string_radix(16, None), "(f.000 5.000)");
let c3 = Complex::with_val(53, (10, -4));
assert_eq!(c3.to_string_radix(10, Some(3)), "(1.00e1 -4.00)");
assert_eq!(c3.to_string_radix(5, Some(3)), "(2.00e1 -4.00)");

`pub fn to_string_radix_round( &self, radix: i32, num_digits: Option<usize>, round: (Round, Round) ) -> String`
[src]

Returns a string representation of the value for the specified radix applying the specified rounding method.

The exponent is encoded in decimal. If the number of digits is not specified, the output string will have enough precision such that reading it again will give the exact same number.

Panics

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

Examples

use rug::Complex;
use rug::float::Round;
let c = Complex::with_val(10, 10.4);
let down = (Round::Down, Round::Down);
let nearest = (Round::Nearest, Round::Nearest);
let up = (Round::Up, Round::Up);
let nd = c.to_string_radix_round(10, None, down);
assert_eq!(nd, "(1.0406e1 0.0)");
let nu = c.to_string_radix_round(10, None, up);
assert_eq!(nu, "(1.0407e1 0.0)");
let sd = c.to_string_radix_round(10, Some(2), down);
assert_eq!(sd, "(1.0e1 0.0)");
let sn = c.to_string_radix_round(10, Some(2), nearest);
assert_eq!(sn, "(1.0e1 0.0)");
let su = c.to_string_radix_round(10, Some(2), up);
assert_eq!(su, "(1.1e1 0.0)");

`pub fn as_raw(&self) -> *const mpc_t`
[src]

Returns a pointer to the inner MPC complex number.

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

Examples

fn main() {
    let c = Complex::with_val(53, (-14.5, 3.25));
    let m_ptr = c.as_raw();
    unsafe {
        let re_ptr = mpc::realref_const(m_ptr);
        let re = mpfr::get_d(re_ptr, mpfr::rnd_t::RNDN);
        assert_eq!(re, -14.5);
        let im_ptr = mpc::imagref_const(m_ptr);
        let im = mpfr::get_d(im_ptr, mpfr::rnd_t::RNDN);
        assert_eq!(im, 3.25);

    // c is still valid
    assert_eq!(c, (-14.5, 3.25));
}

`pub fn real(&self) -> &Float`
[src]

`pub fn as_neg(&self) -> BorrowComplex`
[src]

Borrows a negated copy of the Complex number.

The returned object implements Deref<Target = Complex>.

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

Examples

use rug::Complex;
let c = Complex::with_val(53, (4.2, -2.3));
let neg_c = c.as_neg();
assert_eq!(*neg_c, (-4.2, 2.3));
// methods taking &self can be used on the returned object
let reneg_c = neg_c.as_neg();

assert_eq!(*reneg_c, c);

`pub fn as_conj(&self) -> BorrowComplex`
[src]

Borrows a conjugate copy of the Complex number.

The returned object implements Deref<Target = Complex>.

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

Examples

use rug::Complex;
let c = Complex::with_val(53, (4.2, -2.3));
let conj_c = c.as_conj();
assert_eq!(*conj_c, (4.2, 2.3));

assert_eq!(*reconj_c, c);

`pub fn as_mul_i(&self, negative: bool) -> BorrowComplex`
[src]

Borrows a rotated copy of the Complex number.

The returned object implements Deref<Target = Complex>.

This method operates by performing some shallow copying; unlike the mul_i method and friends, this method swaps the precision of the real and imaginary parts if they have unequal precisions.

Examples

use rug::Complex;
let c = Complex::with_val(53, (4.2, -2.3));
let mul_i_c = c.as_mul_i(false);
assert_eq!(*mul_i_c, (2.3, 4.2));
// methods taking &self can be used on the returned object
let mul_ii_c = mul_i_c.as_mul_i(false);
assert_eq!(*mul_ii_c, (-4.2, 2.3));
let mul_1_c = mul_i_c.as_mul_i(true);

let one_neg0 = one_neg0_c.as_ord();
let one_pos0_c = Complex::with_val(53, (1, Special::Zero));
let one_pos0 = one_pos0_c.as_ord();
assert_eq!(one_neg0.cmp(one_pos0), Ordering::Less);

let zero_inf_s = (Special::Zero, Special::Infinity);
let zero_inf_c = Complex::with_val(53, zero_inf_s);
let zero_inf = zero_inf_c.as_ord();
assert_eq!(one_pos0.cmp(zero_inf), Ordering::Greater);

`pub fn eq0(&self) -> bool`

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

Examples

use rug::Complex;
let c = Complex::with_val(53, (1, 1));
let asinh = Complex::with_val(53, c.asinh_ref());
let expected = Complex::with_val(53, (1.0613, 0.6662));
assert!(*(asinh - expected).abs().real() < 0.0001);

`pub fn acosh_ref(&self) -> AcoshIncomplete`
[src]

Computes the inverse hyperbolic cosine.

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

Examples

use rug::Complex;
let c = Complex::with_val(53, (1, 1));
let acosh = Complex::with_val(53, c.acosh_ref());
let expected = Complex::with_val(53, (1.0613, 0.9046));
assert!(*(acosh - expected).abs().real() < 0.0001);

`pub fn atanh_ref(&self) -> AtanhIncomplete`
[src]

Computes the inverse hyperbolic tangent.

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

Examples

use rug::Complex;
let c = Complex::with_val(53, (1, 1));
let atanh = Complex::with_val(53, c.atanh_ref());
let expected = Complex::with_val(53, (0.4024, 1.0172));
assert!(*(atanh - expected).abs().real() < 0.0001);
