Trait float_cmp::Ulps

pub trait Ulps {
    type U: Copy + NumCast;

    // Required methods
    fn ulps(&self, other: &Self) -> <Self as Ulps>::U;
    fn next(&self) -> Self;
    fn prev(&self) -> Self;
}

A trait for floating point numbers which computes the number of representable values or ULPs (Units of Least Precision) that separate the two given values.

Required Associated Types

type U: Copy + NumCast

Required Methods

fn ulps(&self, other: &Self) -> <Self as Ulps>::U

The number of representable values or ULPs (Units of Least Precision) that separate self and other. The result U is an integral value, and will be zero if self and other are exactly equal.

fn next(&self) -> Self

The next representable number above this one

fn prev(&self) -> Self

The previous representable number below this one

Object Safety

This trait is not object safe.
