NAME
       cbrt, cbrtf, cbrtl - cube root function

SYNOPSIS

       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)):

       cbrt():
	   _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
	       || _XOPEN_SOURCE >= 500
	       || /* Since glibc 2.19: */ _DEFAULT_SOURCE
	       || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
       cbrtf(), cbrtl():
	   _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

	       || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

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

RETURN VALUE
       These functions return the cube root of x.

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

ERRORS
       No errors occur.
