Function `round_ties_even`

const fn round_ties_even(x: f64) -> f64

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

Examples

#![feature(core_float_math)]

use core::f64;

let f = 3.3_f64;
let g = -3.3_f64;
let h = 3.5_f64;
let i = 4.5_f64;

assert_eq!(f64::math::round_ties_even(f), 3.0);
assert_eq!(f64::math::round_ties_even(g), -3.0);
assert_eq!(f64::math::round_ties_even(h), 4.0);
assert_eq!(f64::math::round_ties_even(i), 4.0);

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