Description:
------------
infact the problem occurs on PHP 5.2.3

I want to simply return a float multiplied by a million, and force it to an integer value to avoid php returns int in weird format (2.9E+06 for example), and it doesn't return the correct value.

This is very strange as it seems to occurs only on the '2.09' value : it's ok with 1.09 and 3.09, 2.19, 2.091 and 2.089, etc...


Reproduce code:
---------------
$cpc = '2.09';

echo $cpc * 1000000; // returns correct value : 2090000
echo "<br/>";
echo (int)($cpc * 1000000); // returns 2089999 !!
echo "<br/>";
echo (int)($cpc * 1000 * 1000); // return correct value.

Expected result:
----------------
2090000
2090000
2090000

Actual result:
--------------
2090000
2089999
2090000
