Function `floor`

#[must_use = "method returns a new number and does not mutate the original value"]
pub const fn floor(x: f64) -> f64

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

Examples

#![feature(core_float_math)]

use core::f64;

let f = 3.7_f64;
let g = 3.0_f64;
let h = -3.7_f64;

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

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