pub struct FixedI16<const FRAC: i32> { /* private fields */ }
Expand description

A 16-bit signed number with FRAC fractional bits.

The number has 16 bits, of which f = FRAC are fractional bits and 16 − f are integer bits. The value x can lie in the range −215/2f ≤ x < 215/2f. The difference between successive numbers is constant throughout the range: Δ = 1/2f.

For FixedI16<0>, f = 0 and Δ = 1, and the fixed-point number behaves like an i16 with the value lying in the range −215 ≤ x < 215. For FixedI16<16>, f = 16 and Δ = 1/216, and the value lies in the range −1/2 ≤ x < 1/2.

FixedI16<FRAC> has the same size, alignment and ABI as i16; it is #[repr(transparent)] with i16 as the only non-zero-sized field.

Examples

#![feature(generic_const_exprs)]

use fixed::FixedI16;
let eleven = FixedI16::<3>::from_num(11);
assert_eq!(eleven, FixedI16::<3>::from_bits(11 << 3));
assert_eq!(eleven, 11);
assert_eq!(eleven.to_string(), "11");
let two_point_75 = eleven / 4;
assert_eq!(two_point_75, FixedI16::<3>::from_bits(11 << 1));
assert_eq!(two_point_75, 2.75);
assert_eq!(two_point_75.to_string(), "2.8");

Implementations

The items in this block are implemented for all values of FRAC.

Zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::ZERO, Fix::from_bits(0));

The difference between any two successive representable numbers, Δ.

If the number has f = FRAC fractional bits, then Δ = 1/2f.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::DELTA, Fix::from_bits(1));
// binary 0.0001 is decimal 0.0625
assert_eq!(Fix::DELTA, 0.0625);

The smallest value that can be represented.

If the number has f = FRAC fractional bits, then the minimum is −215/2f.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::MIN, Fix::from_bits(i16::MIN));

The largest value that can be represented.

If the number has f = FRAC fractional bits, then the maximum is (215 − 1)/2f.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::MAX, Fix::from_bits(i16::MAX));

true because the FixedI16 type is signed.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert!(Fix::IS_SIGNED);

The number of integer bits.

Note that INT_BITS + FRAC_BITS = 16. Both INT_BITS and FRAC_BITS can be negative.

  • When INT_BITS < 0 and FRAC_BITS > 16, the magnitude can be very large and DELTA > 1.
  • When INT_BITS > 16 and FRAC_BITS < 0, the magnitude can be very small and DELTA < 2−16.
Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<6>;
assert_eq!(Fix::INT_BITS, 16 - 6);

The number of fractional bits.

Note that INT_BITS + FRAC_BITS = 16. Both INT_BITS and FRAC_BITS can be negative.

  • When INT_BITS < 0 and FRAC_BITS > 16, DELTA > 1. That is, the magnitude can be very large.
  • When INT_BITS > 16 and FRAC_BITS < 0, DELTA < 2−16. That is, the magnitude can be very small.
Examples

Creates a fixed-point number from another number.

The other number can be:

  • Another fixed-point number. Any extra fractional bits are discarded, which rounds towards −∞.
  • An integer of type i8, i16, i32, i64, i128, isize, u8, u16, u32, u64, u128, or usize.

  • Any other number src for which ToFixed is implemented, in which case this method returns src.to_fixed().
Panics

For floating-point numbers, panics if the value is not finite.

When debug assertions are enabled, panics if the value does not fit. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_from_num instead.

  • Another fixed-point number. Any extra fractional bits are discarded, which rounds towards −∞.
  • An integer of type i8, i16, i32, i64, i128, isize, u8, u16, u32, u64, u128, or usize. Any fractional bits are discarded, which rounds towards −∞.
  • A floating-point number of type f16, bf16, f32, f64 or F128. For this conversion, the method rounds to the nearest, with ties rounding to even.
  • Any other type Dst for which FromFixed is implemented, in which case this method returns Dst::unwrapped_from_fixed(self).
Panics

Panics if the value does not fit.

Examples

assert_eq!(one_point_625.overflowing_to_num::<f32>(), (1.625f32, false));

Returns the integer part.

Note that since the numbers are stored in two’s complement, negative numbers with non-zero fractional parts will be rounded towards −∞, except in the case where there are no integer bits, that is FixedI16<U16>, where the return value is always zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
// 0010.0000
let two = Fix::from_num(2);
// 0010.0100
let two_and_quarter = two + two / 8;
assert_eq!(two_and_quarter.int(), two);
// 1101.0000
let three = Fix::from_num(3);
// 1101.1100
assert_eq!((-two_and_quarter).int(), -three);

Returns the fractional part.

Note that since the numbers are stored in two’s complement, the returned fraction will be non-negative for negative numbers, except in the case where there are no integer bits, that is FixedI16<U16> where the return value is always equal to self.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
// 0000.0100
let quarter = Fix::ONE / 4;
// 0010.0100
let two_and_quarter = quarter * 9;
assert_eq!(two_and_quarter.frac(), quarter);
// 0000.1100
let three_quarters = quarter * 3;
// 1101.1100
assert_eq!((-two_and_quarter).frac(), three_quarters);

Rounds to the next integer towards 0.

Note that for negative numbers, this is different from truncating/discarding the fractional bits. This is because in two’s-complement representations, the value of all the bits except for the most significant bit is positive; discarding positive bits would round towards −∞ unlike this method which rounds towards zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(2.1).round_to_zero(), Fix::from_num(2));
assert_eq!(Fix::from_num(2.9).round_to_zero(), Fix::from_num(2));
assert_eq!(Fix::from_num(-2.1).round_to_zero(), Fix::from_num(-2));
assert_eq!(Fix::from_num(-2.9).round_to_zero(), Fix::from_num(-2));

Rounds to the next integer towards +∞.

Panics

When debug assertions are enabled, panics if the result does not fit. When debug assertions are not enabled, the wrapped result can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_ceil instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(2.5).ceil(), Fix::from_num(3));
assert_eq!(Fix::from_num(-2.5).ceil(), Fix::from_num(-2));

Rounds to the next integer towards −∞.

Panics

When debug assertions are enabled, panics if the result does not fit. When debug assertions are not enabled, the wrapped result can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_floor instead.

Overflow can only occur when there are zero integer bits.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(2.5).floor(), Fix::from_num(2));
assert_eq!(Fix::from_num(-2.5).floor(), Fix::from_num(-3));

Rounds to the nearest integer, with ties rounded away from zero.

Panics

When debug assertions are enabled, panics if the result does not fit. When debug assertions are not enabled, the wrapped result can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_round instead.

assert_eq!(bits.rotate_right(3), rot);
assert_eq!(Fix::from_bits(bits).rotate_right(3), Fix::from_bits(rot));

Returns true if the number is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert!(Fix::ZERO.is_zero());
assert!(!Fix::from_num(5).is_zero());

Returns true if the number is > 0.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert!(Fix::from_num(5).is_positive());
assert!(!Fix::ZERO.is_positive());
assert!(!Fix::from_num(-5).is_positive());

Returns true if the number is < 0.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert!(!Fix::from_num(5).is_negative());
assert!(!Fix::ZERO.is_negative());
assert!(Fix::from_num(-5).is_negative());

Multiplies two fixed-point numbers and returns a wider type to retain all precision.

If self has f fractional bits and 16 − f integer bits, and rhs has g fractional bits and 16 − g integer bits, then the returned fixed-point number will have f + g fractional bits and 32 − f − g integer bits.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
// decimal: 1.25 × 1.0625 = 1.328_125
// binary: 1.01 × 1.0001 = 1.010101
let a = FixedI16::<2>::from_num(1.25);
let b = FixedI16::<4>::from_num(1.0625);
assert_eq!(a.wide_mul(b), 1.328_125);

Multiplies an unsigned fixed-point number and returns a wider signed type to retain all precision.

If self has f fractional bits and 16 − f integer bits, and rhs has g fractional bits and 16 − g integer bits, then the returned fixed-point number will have f + g fractional bits and 32 − f − g integer bits.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedU16};
// decimal: -1.25 × 1.0625 = -1.328_125
// binary: -1.01 × 1.0001 = -1.010101
let a = FixedI16::<2>::from_num(-1.25);
let b = FixedU16::<4>::from_num(1.0625);
assert_eq!(a.wide_mul_unsigned(b), -1.328_125);

Divides two fixed-point numbers and returns a wider type to retain more precision.

If self has f fractional bits and 16 − f integer bits, and rhs has g fractional bits and 16 − g integer bits, then the returned fixed-point number will have 16 + f − g fractional bits and 16 − f + g integer bits.

Warning: While most cases of overflow are avoided using this method, dividing MIN by -DELTA will still result in panic due to overflow. The alternative wide_sdiv method avoids this by sacrificing one fractional bit in the return type.

Panics

Panics if the divisor is zero or on overflow. Overflow can only occur when dividing MIN by -DELTA.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedI32};
// decimal: 4.625 / 0.03125 = 148
// binary: 100.101 / 0.00001 = 10010100
let a = FixedI16::<3>::from_num(4.625);
let b = FixedI16::<5>::from_num(0.03125);
let ans: FixedI32<14> = a.wide_div(b);
assert_eq!(ans, 148);

The following panics because of overflow.

ⓘ
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let _overflow = Fix::MIN.wide_div(-Fix::DELTA);

Divides two fixed-point numbers and returns a wider type to retain more precision.

If self has f fractional bits and 16 − f integer bits, and rhs has g fractional bits and 16 − g integer bits, then the returned fixed-point number will have 15 + f − g fractional bits and 17 − f + g integer bits.

This is similar to the wide_div method but sacrifices one fractional bit to avoid overflow.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedI32};
// decimal: 4.625 / 0.03125 = 148
// binary: 100.101 / 0.00001 = 10010100
let a = FixedI16::<4>::from_num(4.625);
let b = FixedI16::<5>::from_num(0.03125);
let ans: FixedI32<14> = a.wide_sdiv(b);
assert_eq!(ans, 148);

Unlike wide_div, dividing MIN by -DELTA does not overflow.

#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedI32};
type Fix = FixedI16<4>;
type DFix = FixedI32<15>;
assert_eq!(Fix::MIN.wide_sdiv(-Fix::DELTA), (DFix::MIN / 2).abs());

Divides by an unsigned fixed-point number and returns a wider signed type to retain more precision.

If self has f fractional bits and 16 − f integer bits, and rhs has g fractional bits and 16 − g integer bits, then the returned fixed-point number will have 16 + f − g fractional bits and 16 − f + g integer bits.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedI32, FixedU16};
// decimal: -4.625 / 0.03125 = -148
// binary: -100.101 / 0.00001 = -10010100
let a = FixedI16::<3>::from_num(-4.625);
let b = FixedU16::<5>::from_num(0.03125);
let ans: FixedI32<14> = a.wide_div_unsigned(b);
assert_eq!(ans, -148);

Multiply and add. Returns self × mul + add.

For some cases, the product self × mul would overflow on its own, but the final result self × mul + add is representable; in these cases this method returns the correct result without overflow.

The mul parameter can have a fixed-point type like self but with a different number of fractional bits.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_mul_add instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(
    Fix::from_num(4).mul_add(Fix::from_num(0.5), Fix::from_num(3)),
    Fix::from_num(5)
);
// MAX × 1.5 - MAX = MAX / 2, which does not overflow
assert_eq!(Fix::MAX.mul_add(Fix::from_num(1.5), -Fix::MAX), Fix::MAX / 2);

Adds self to the product a × b.

For some cases, the product a × b would overflow on its own, but the final result self + a × b is representable; in these cases this method returns the correct result without overflow.

The a and b parameters can have a fixed-point type like self but with a different number of fractional bits.

The mul_acc method performs the same operation as this method but mutates self instead of returning the result.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_add_prod instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(3).add_prod(Fix::from_num(4), Fix::from_num(0.5)), 5);
// -MAX + MAX × 1.5 = MAX / 2, which does not overflow
assert_eq!((-Fix::MAX).add_prod(Fix::MAX, Fix::from_num(1.5)), Fix::MAX / 2);

Multiply and accumulate. Adds (a × b) to self.

For some cases, the product a × b would overflow on its own, but the final result self + a × b is representable; in these cases this method saves the correct result without overflow.

The a and b parameters can have a fixed-point type like self but with a different number of fractional bits.

The add_prod method performs the same operation as this method but returns the result instead of mutating self.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_mul_acc instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let mut acc = Fix::from_num(3);
acc.mul_acc(Fix::from_num(4), Fix::from_num(0.5));
assert_eq!(acc, 5);

// MAX × 1.5 - MAX = MAX / 2, which does not overflow
acc = -Fix::MAX;
acc.mul_acc(Fix::MAX, Fix::from_num(1.5));
assert_eq!(acc, Fix::MAX / 2);

Remainder for Euclidean division.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(7.5).rem_euclid(Fix::from_num(2)), Fix::from_num(1.5));
assert_eq!(Fix::from_num(-7.5).rem_euclid(Fix::from_num(2)), Fix::from_num(0.5));

Returns the absolute value.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let five = Fix::from_num(5);
let minus_five = Fix::from_num(-5);
assert_eq!(five.abs(), five);
assert_eq!(minus_five.abs(), five);

Returns the absolute value using an unsigned type without any wrapping or panicking.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedU16};
type Fix = FixedI16<4>;
type UFix = FixedU16<4>;
assert_eq!(Fix::from_num(-5).unsigned_abs(), UFix::from_num(5));
// min_as_unsigned has only highest bit set
let min_as_unsigned = UFix::ONE << (UFix::INT_BITS - 1);
assert_eq!(Fix::MIN.unsigned_abs(), min_as_unsigned);

Returns the distance from self to other.

The distance is the absolute value of the difference.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_dist instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::ONE.dist(Fix::from_num(5)), Fix::from_num(4));
assert_eq!(Fix::NEG_ONE.dist(Fix::from_num(2)), Fix::from_num(3));

Returns the distance from self to other using an unsigned type without any wrapping or panicking.

The distance is the absolute value of the difference.

Examples
#![feature(generic_const_exprs)]

use fixed::{FixedI16, FixedU16};
type Fix = FixedI16<4>;
type UFix = FixedU16<4>;
assert_eq!(Fix::NEG_ONE.unsigned_dist(Fix::from_num(2)), UFix::from_num(3));
assert_eq!(Fix::MIN.unsigned_dist(Fix::MAX), UFix::MAX);

Returns a number representing the sign of self.

Panics

When debug assertions are enabled, this method panics

  • if the value is positive and the fixed-point number has zero or one integer bits such that it cannot hold the value 1.
  • if the value is negative and the fixed-point number has zero integer bits, such that it cannot hold the value −1.

When debug assertions are not enabled, the wrapped value can be returned in those cases, but it is not considered a breaking change if in the future it panics; using this method when 1 and −1 cannot be represented is almost certainly a bug.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(5).signum(), 1);
assert_eq!(Fix::ZERO.signum(), 0);
assert_eq!(Fix::from_num(-5).signum(), -1);

Returns the absolute value of the difference between self and other using an unsigned type without any wrapping or panicking.

This method is the same as unsigned_dist for signed fixed-point numbers.

Returns the mean of self and other.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(3).mean(Fix::from_num(4)), Fix::from_num(3.5));
assert_eq!(Fix::from_num(-3).mean(Fix::from_num(4)), Fix::from_num(0.5));

Returns the smallest multiple of other that is ≥ self if other is positive, and the largest multiple of other that is ≤ self if other is negative.

Panics

Panics if other is zero.

When debug assertions are enabled, this method also panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_next_multiple_of instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(
    Fix::from_num(4).next_multiple_of(Fix::from_num(1.5)),
    Fix::from_num(4.5)
);
assert_eq!(
    Fix::from_num(4).next_multiple_of(Fix::from_num(-1.5)),
    Fix::from_num(3)
);

Inverse linear interpolation between start and end.

The computed value can have a fixed-point type like self but with a different number of fractional bits.

Returns (self − start) / (end − start). This is 0 when self = start, and 1 when self = end.

Panics

Panics when start = end.

When debug assertions are enabled, this method also panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_inv_lerp instead.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let start = Fix::from_num(2);
let end = Fix::from_num(3.5);

assert_eq!(Fix::from_num(2).inv_lerp::<4>(start, end), 0);
assert_eq!(Fix::from_num(2.75).inv_lerp::<4>(start, end), 0.5);
assert_eq!(Fix::from_num(3.5).inv_lerp::<4>(start, end), 1);
assert_eq!(Fix::from_num(5).inv_lerp::<4>(start, end), 2);

Addition with an unsigned fixed-point number.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_add_unsigned instead.

use fixed::{FixedI16, FixedU16};
type Fix = FixedI16<4>;
type UFix = FixedU16<4>;
assert_eq!(Fix::from_num(-5).add_unsigned(UFix::from_num(3)), -2);

Subtraction with an unsigned fixed-point number.

Panics

When debug assertions are enabled, this method panics if the result overflows. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_sub_unsigned instead.

assert_eq!(Fix::from_num(3).sub_unsigned(UFix::from_num(5)), -2);

Bitwise NOT. Usable in constant context.

This is equivalent to the ! operator and Not::not, but can also be used in constant context. Unless required in constant context, use the operator or trait instead.

Planned deprecation

This method will be deprecated when the ! operator and the Not trait are usable in constant context.

Examples

const NOT_A: Fix = A.const_not();
assert_eq!(NOT_A, !A);

Bitwise AND. Usable in constant context.

This is equivalent to the & operator and BitAnd::bitand, but can also be used in constant context. Unless required in constant context, use the operator or trait instead.

assert_eq!(Fix::MAX.checked_add(Fix::ONE), None);

Checked subtraction. Returns the difference, or None on overflow.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;

assert_eq!(Fix::from_num(1.5).checked_rem(Fix::ZERO), None);

Checked multiply and add. Returns self × mul + add, or None on overflow.

For some cases, the product self × mul would overflow on its own, but the final result self × mul + add is representable; in these cases this method returns the correct result without overflow.

The mul parameter can have a fixed-point type like self but with a different number of fractional bits.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(
    Fix::from_num(4).checked_mul_add(Fix::from_num(0.5), Fix::from_num(3)),

);
assert_eq!(Fix::MAX.checked_mul_add(Fix::ONE, Fix::ZERO), Some(Fix::MAX));

// MAX × 1.5 - MAX = MAX / 2, which does not overflow
assert_eq!(Fix::MAX.checked_mul_add(Fix::from_num(1.5), -Fix::MAX), Some(Fix::MAX / 2));

Adds self to the product a × b, returning None on overflow.

The a and b parameters can have a fixed-point type like self but with a different number of fractional bits.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;

    Some(Fix::MAX / 2)
);

Checked multiply and accumulate. Adds (a × b) to self, or returns None on overflow.

Like all other checked methods, this method wraps the successful return value in an Option. Since the unchecked mul_acc method does not return a value, which is equivalent to returning (), this method wraps () into Some(()) on success.

When overflow occurs, self is not modified and retains its previous value.

For some cases, the product a × b would overflow on its own, but the final result self + a × b is representable; in these cases this method saves the correct result without overflow.

The a and b parameters can have a fixed-point type like self but with a different number of fractional bits.

Examples

assert_eq!(Fix::MIN.checked_dist(Fix::ZERO), None);

Checked signum. Returns a number representing the sign of self, or None on overflow.

Overflow can only occur

  • if the value is positive and the fixed-point number has zero or one integer bits such that it cannot hold the value 1.
  • if the value is negative and the fixed-point number has zero integer bits, such that it cannot hold the value −1.

#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<12>;
assert_eq!(Fix::from_num(7.5).unwrapped_rem_euclid_int(2), Fix::from_num(1.5));
assert_eq!(Fix::from_num(-7.5).unwrapped_rem_euclid_int(2), Fix::from_num(0.5));

The following panics because of overflow.

ⓘ
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<12>;
// -8 ≤ Fix < 8, so the answer 12.5 overflows
let _overflow = Fix::from_num(-7.5).unwrapped_rem_euclid_int(20);

Linear interpolation between start and end, panicking on overflow.

The interpolated value is start + self × (end − start). This is start when self = 0, end when self = 1, and linear interpolation for all other values of self. Linear extrapolation is performed if self is not in the range 0 ≤ x ≤ 1.

Panics

Panics if the result overflows.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(0.5).unwrapped_lerp(Fix::ZERO, Fix::MAX), Fix::MAX / 2);

The following panics because of overflow.

ⓘ
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let _overflow = Fix::from_num(1.5).unwrapped_lerp(Fix::ZERO, Fix::MAX);

Overflowing division.

Returns a tuple of the quotient and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned.

Panics

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let one_point_5 = Fix::from_bits(0b11 << (4 - 1));
assert_eq!(Fix::from_num(3).overflowing_div(Fix::from_num(2)), (one_point_5, false));
let quarter = Fix::ONE / 4;
let wrapped = Fix::from_bits(!0 << 2);
assert_eq!(Fix::MAX.overflowing_div(quarter), (wrapped, true));

Overflowing reciprocal.

Returns a tuple of the reciprocal and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned.

Panics

Panics if the fixed-point number is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
// only one integer bit
type Small = FixedI16<15>;
assert_eq!(Fix::from_num(0.25).overflowing_recip(), (Fix::from_num(4), false));
assert_eq!(Small::from_num(0.25).overflowing_recip(), (Small::ZERO, true));

Overflowing Euclidean division.

Returns a tuple of the quotient and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
let check = Fix::from_num(3);
assert_eq!(Fix::from_num(7.5).overflowing_div_euclid(Fix::from_num(2)), (check, false));
let wrapped = Fix::MAX.wrapping_mul_int(4).round_to_zero();
assert_eq!(Fix::MAX.overflowing_div_euclid(Fix::from_num(0.25)), (wrapped, true));

Overflowing Euclidean division by an integer.

Returns a tuple of the quotient and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned. Overflow can only occur when dividing the minimum value by −1.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<4>;
assert_eq!(Fix::from_num(7.5).overflowing_div_euclid_int(2), (Fix::from_num(3), false));

let wrapped = Fix::MIN.round_to_zero();
assert_eq!(Fix::MIN.overflowing_div_euclid_int(-1), (wrapped, true));

Remainder for Euclidean division by an integer.

Returns a tuple of the remainder and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned.

Note that while remainder for Euclidean division cannot be negative, the wrapped value can be negative.

Panics

Panics if the divisor is zero.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedI16;
type Fix = FixedI16<12>;
assert_eq!(Fix::from_num(7.5).overflowing_rem_euclid_int(2), (Fix::from_num(1.5), false));
assert_eq!(Fix::from_num(-7.5).overflowing_rem_euclid_int(2), (Fix::from_num(0.5), false));
// -8 ≤ Fix < 8, so the answer 12.5 wraps to -3.5
assert_eq!(Fix::from_num(-7.5).overflowing_rem_euclid_int(20), (Fix::from_num(-3.5), true));

Overflowing linear interpolation between start and end.

Returns a tuple of the result and a bool indicationg whether an overflow has occurred. On overflow, the wrapped value is returned.

The interpolated value is start + self × (end − start). This is start when self = 0, end when self = 1, and linear interpolation for all other values of self. Linear extrapolation is performed if self is not in the range 0 ≤ x ≤ 1.

Converts a fixed-point number.

Any extra fractional bits are discarded, which rounds towards −∞.

Panics

When debug assertions are enabled, panics if the value does not fit. When debug assertions are not enabled, the wrapped value can be returned, but it is not considered a breaking change if in the future it panics; if wrapping is required use wrapping_to_fixed instead.

Converts a fixed-point number if it fits, otherwise returns None.
