Trait approx::UlpsEq

pub trait UlpsEq<Rhs = Self>: AbsDiffEq<Rhs>where
    Rhs: ?Sized,{
    fn default_max_ulps() -> u32;
    fn ulps_eq(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool;

    fn ulps_ne(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool { ... }
}

Equality comparisons between two numbers using both the absolute difference and ULPs (Units in Last Place) based comparisons.

Required Methods

fn default_max_ulps() -> u32

The default ULPs to tolerate when testing values that are far-apart.

This is used when no max_ulps value is supplied to the [ulps_eq] macro.

fn ulps_eq(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool

A test for equality that uses units in the last place (ULP) if the values are far apart.

Provided Methods

fn ulps_ne(&self, other: &Rhs, epsilon: Self::Epsilon, max_ulps: u32) -> bool

The inverse of UlpsEq::ulps_eq.
