Bug description:Float to integer conversion

Description:
------------
Hi,

I've read the warning about float on documentation 
http://php.net/manual/fr/language.types.float.php
but for simple
computing it should be nice if Php return value like other languages
(Python & Java).

The computing (int)( 103.24 * 6 * 10**2) should return 61944 nor 61943.

I've done the same with Java & Python (converting float result to
integer) and get the right result: 61944



Test script:
---------------
php -r 'echo (int)( 103.24 * 6 * 10**2),"\n";'


Expected result:
----------------
61944

Actual result:
--------------
61943
