Computes the cube root.
#include <math.h> float cbrtf (x) float x; long double cbrtl (x) long double x; double cbrt (x) double x;
The cbrtf, cbrtl, and cbrt subroutines compute the real cube root of the x argument.
| x | Specifies the value to be computed. |
Upon successful completion, the cbrtf, cbrtl, and cbrt subroutines return the cube root of x.
If x is NaN, an NaN is returned.
If x is ±0 or ±Inf, x is returned.
