Module assert_approx 

Assert for approximations.

These macros compare numbers, such as two floating point numbers, where one number may be very close to another number but not quite equal.

• assert_approx_eq!(a, b) ≈ a is approximately equal to b

• assert_approx_ne!(a, b) ≈ a is approximately not equal to b

• assert_approx_eq_with_absolute_error!(a, b, Δ) ≈ a is approximately equal to b by using absolute error a.k.a. delta.

• assert_approx_ne_with_absolute_error!(a, b, Δ) ≈ a is approximately not equal to b by using absolute error a.k.a. delta.

• assert_approx_eq_with_relative_error!(a, b, ε) ≈ a is approximately equal to b by using relative error a.k.a. epsilon.

• assert_approx_ne_with_relative_error!(a, b, ε) ≈ a is approximately not equal to b by using relative error a.k.a. epsilon.

Example

use assertables::*;

let a: f32 = 1.0000001;
let b: f32 = 1.0000011;
assert_approx_eq!(a, b);
