#include <math.h>

double cbrt(double x);
float cbrtf(float x);
long double cbrtl(long double x);

Link with -lm.

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

These functions return the (real) cube root of x. This function cannot fail; every representable real value has a representable real cube root.

These functions return the cube root of x.

If x is +0, -0, positive infinity, negative infinity, or NaN, x is returned.
