Experimental version of rem_euclid in core. See f64::rem_euclid for details.

Examples

#![feature(core_float_math)]

use core::f64;

let a: f64 = 7.0;
let b = 4.0;
assert_eq!(f64::math::rem_euclid(a, b), 3.0);
assert_eq!(f64::math::rem_euclid(-a, b), 1.0);
assert_eq!(f64::math::rem_euclid(a, -b), 3.0);
assert_eq!(f64::math::rem_euclid(-a, -b), 1.0);
// limitation due to round-off error
assert!(f64::math::rem_euclid(-f64::EPSILON, 3.0) != 0.0);

This standalone function is for testing only. It will be stabilized as an inherent method.
