Function cbrt

pub fn cbrt(x: f64) -> f64

🔬This is a nightly-only experimental API. (core_float_math)

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

Examples

#![feature(core_float_math)]

use core::f64;

let x = 8.0_f64;

// x^(1/3) - 2 == 0
let abs_difference = (f64::cbrt(x) - 2.0).abs();

assert!(abs_difference < 1e-10);

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