cbrt, cbrtf, cbrtl − cube root function

#include <math.h>

double cbrt(double x);

float cbrtf(float x);

long double cbrtl(long double x);

The cbrt() function returns the (real) cube root of x. This function cannot fail; every representable real value has a representable real cube root.

cbrt() was a GNU extension. It is now a C99 requirement.
