Bug description:Wrong Answer to a fairly standard calculation
Description:
------------
The calculation in the test script should return 34, but yet is
returning back 33.999999999998, which is very odd.
Test script:
---------------
<?php
//expecting 34
var_dump((40120.7 - 36346.0)-3740.7);
?>
Expected result:
----------------
Return back of the value of 34.
Actual result:
--------------
33.999999999998
