cbrt

Syntax

#include <math.h> double cbrt(double x);

Description

This function computes the cube root of x. It is faster and more accurate to call cbrt(x) than to call pow(x, 1./3.).

Return Value

The cube root of x. If the value of x is NaN, the return value is NaN and errno is set to EDOM. Infinite arguments are returned unchanged, without setting errno.
