Trait float_cmp::ApproxEqUlps

pub trait ApproxEqUlps {
    type Flt: Ulps;
    fn approx_eq_ulps(&self, other: &Self, ulps: <Self::Flt as Ulps>::U) -> bool;

    fn approx_ne_ulps(&self, other: &Self, ulps: <Self::Flt as Ulps>::U) -> bool { ... }
}

ApproxEqUlps is a trait for approximate equality comparisons. The associated type Flt is a floating point type which implements Ulps, and is required so that this trait can be implemented for compound types (e.g. vectors), not just for the floats themselves.

Associated Types

type Flt: Ulps

Required Methods

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

This method tests for self and other values to be approximately equal within ULPs (Units of Least Precision) floating point representations.

Provided Methods

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

This method tests for self and other values to be not approximately equal within ULPs (Units of Least Precision) floating point representations.
