       Link with -lm.

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

       cbrt(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 || _ISOC99_SOURCE; or cc -std=c99
       cbrtf(), cbrtl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; 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
