NAME
       cbrt, cbrtf, cbrtl - cube root function

SYNOPSIS
       #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)):

       cbrt():
	   _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 ||
	   _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED || _ISOC99_SOURCE ||
	   _POSIX_C_SOURCE >= 200112L;
	   or cc -std=c99
       cbrtf(), cbrtl():
	   _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
	   _ISOC99_SOURCE || _POSIX_C_SOUCE >= 200112L;
	   or cc -std=c99

DESCRIPTION
       The cbrt() function returns 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.

CONFORMING TO
