Struct Ratio 

pub struct Ratio { /* private fields */ }

An exact ratio of two integers, reduced to lowest terms on construction.

Unlike a float, a Ratio compares and hashes exactly: two ratios built from different numerator/denominator pairs are equal whenever they denote the same fraction (Ratio::new(1, 2) == Ratio::new(2, 4)), with no rounding or bit-pattern comparison involved. This makes it a good fit for comptime kernel parameters that are always derived from integers (tensor shapes, tile sizes, and the like).

For a value that is not exactly the ratio of two integers, use ComptimeFloat instead.

Implementations

impl Ratio

pub fn new(numerator: usize, denominator: usize) -> Self

Panics

Panics if denominator is zero.

pub fn numerator(self) -> usize

pub fn denominator(self) -> usize

The reduced denominator.

pub fn as_f32(self) -> f32

Convert to an f32.

pub fn as_f64(self) -> f64

Convert to an f64.
