Required Associated Types

type U: Copy

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
