pub struct FixedU32<const FRAC: i32> { /* private fields */ }
Expand description

A 32-bit unsigned number with FRAC fractional bits.

The number has 32 bits, of which f = FRAC are fractional bits and 32 − f are integer bits. The value x can lie in the range 0 ≤ x < 232/2f. The difference between successive numbers is constant throughout the range: Δ = 1/2f.

For FixedU32<0>, f = 0 and Δ = 1, and the fixed-point number behaves like a u32 with the value lying in the range 0 ≤ x < 232. For FixedU32<32>, f = 32 and Δ = 1/232, and the value lies in the range 0 ≤ x < 1.

FixedU32<FRAC> has the same size, alignment and ABI as u32; it is #[repr(transparent)] with u32 as the only non-zero-sized field.

Examples

#![feature(generic_const_exprs)]

use fixed::FixedU32;
let eleven = FixedU32::<3>::from_num(11);
assert_eq!(eleven, FixedU32::<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, FixedU32::<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::FixedU32;
type Fix = FixedU32<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::FixedU32;
type Fix = FixedU32<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.

The minimum of unsigned numbers is 0.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedU32;
type Fix = FixedU32<4>;
assert_eq!(Fix::MIN, Fix::from_bits(u32::MIN));

The largest value that can be represented.

If the number has f = FRAC fractional bits, then the maximum is (232 − 1)/2f.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedU32;
type Fix = FixedU32<4>;
assert_eq!(Fix::MAX, Fix::from_bits(u32::MAX));

false because the FixedU32 type is unsigned.

Examples
#![feature(generic_const_exprs)]

use fixed::FixedU32;
type Fix = FixedU32<4>;
assert!(!Fix::IS_SIGNED);

The number of integer bits.

Note that INT_BITS + FRAC_BITS = 32. Both INT_BITS and FRAC_BITS can be negative.

  • When INT_BITS < 0 and FRAC_BITS > 32, the magnitude can be very large and DELTA > 1.
  • When INT_BITS > 32 and FRAC_BITS < 0, the magnitude can be very small and DELTA < 2−32.
Examples
#![feature(generic_const_exprs)]

use fixed::FixedU32;
type Fix = FixedU32<6>;
assert_eq!(Fix::INT_BITS, 32 - 6);

The number of fractional bits.

Note that INT_BITS + FRAC_BITS = 32. Both INT_BITS and FRAC_BITS can be negative.

  • When INT_BITS < 0 and FRAC_BITS > 32, DELTA > 1. That is, the magnitude can be very large.
  • When INT_BITS > 32 and FRAC_BITS < 0, DELTA < 2−32. That is, the magnitude can be very small.
Examples
#![feature(generic_const_exprs)]

type Fix = FixedU32<6>;
assert_eq!(Fix::FRAC_BITS, 6);

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.
  • 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.

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.

let too_large = FixedU32::<0>::from_bits(0b1101 << (32 - 7));
let _overflow = Fix::unwrapped_from_num(too_large);

Converts a fixed-point number to another number, panicking on overflow.

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 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.

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::FixedU32;
type Fix = FixedU32<4>;
assert_eq!(
    Fix::from_num(4).mul_add(Fix::from_num(0.5), Fix::from_num(3)),
    Fix::from_num(5)
);

Adds self to the product a × b.

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.

type Fix = FixedU32<4>;
assert_eq!(Fix::ONE.dist(Fix::from_num(5)), Fix::from_num(4));

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::FixedU32;

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.
