cbrt, cbrtf, cbrtl - cube root function
#include <math.h>
double cbrt(double x);
float cbrtf(float x);
long double cbrtl(long double x);
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 real cube
root, and rounding it to a representable value never causes overflow nor
underflow.
These functions return the cube root of x
.
If x
is +0, -0, positive infinity, negative infinity, or
NaN, x
is returned.
