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

Examples

#![feature(core_float_math)]

use core::f64;

let x = 3.6_f64;
let y = -3.6_f64;
let abs_difference_x = (f64::math::fract(x) - 0.6).abs();
let abs_difference_y = (f64::math::fract(y) - (-0.6)).abs();

assert!(abs_difference_x < 1e-10);
assert!(abs_difference_y < 1e-10);

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