Function `trunc`

const fn trunc(x: f32) -> f32

Experimental version of trunc in core. See f32::trunc for details.

Examples

#![feature(core_float_math)]

use core::f32;

let f = 3.7_f32;
let g = 3.0_f32;
let h = -3.7_f32;

assert_eq!(f32::math::trunc(f), 3.0);
assert_eq!(f32::math::trunc(g), 3.0);
assert_eq!(f32::math::trunc(h), -3.0);

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