Bug description: Invalid Calculation: 90.99-90.00 = 0.98999999999999 ... when it
should be 0.99
Description:
------------
When calculating 90.99 minus 90.00 it returns 0.98999999999999 which is a
bit big for a simple subtraction of two floats that only have 2 decimal
numbers.
Reproduce code:
---------------
<?php
$calc = 90.99 - 90.00;
print $calc;
?>
Expected result:
----------------
.99
Actual result:
--------------
0.98999999999999
