Description:
------------

From manual page: http://www.php.net/function.gmp-fact

The value returned is not correct when providing decimal input for any PHP version the function
exists in

Test script:
---------------
See https://3v4l.org/fhsSZ

Expected result:
----------------
~496.6 For full result, see https://www.google.com/#q=5.8!

Actual result:
--------------
120 (correct value for input = 5)
