Struct rin::math::Ulps[−][src]

pub struct Ulps<A, B = A> where
    B: ?Sized,
    A: UlpsEq<B> + ?Sized,  {
    pub epsilon: <A as AbsDiffEq<B>>::Epsilon,
    pub max_ulps: u32,
}

The requisite parameters for testing for approximate equality using an ULPs based comparison.

This is not normally used directly, rather via the assert_ulps_{eq|ne}! and ulps_{eq|ne}! macros.

Example

use std::f64;
use approx::Ulps;

Ulps::default().eq(&1.0, &1.0);
Ulps::default().epsilon(f64::EPSILON).eq(&1.0, &1.0);
Ulps::default().max_ulps(4).eq(&1.0, &1.0);
Ulps::default().epsilon(f64::EPSILON).max_ulps(4).eq(&1.0, &1.0);
Ulps::default().max_ulps(4).epsilon(f64::EPSILON).eq(&1.0, &1.0);

Fields

epsilon: <A as AbsDiffEq>::Epsilon

The tolerance to use when testing values that are close together.

max_ulps: u32

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