pub fn fract(x: f64) -> f64🔬This is a nightly-only experimental API. (
core_float_math)Expand description
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::fract(x) - 0.6).abs();
let abs_difference_y = (f64::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.
