Description:
------------
When I multiply 2.30 by 100 and then try to typecast the result as a integer, I get the result 229.

Reproduce code:
---------------
<?php
echo "2.30"*100;
echo "\n";
echo (int)("2.30"*100);
echo "\n";
echo "2.99"*100;
echo "\n";
echo (int)("2.99"*100);
echo "\n";
echo "2.50"*100;
echo "\n";
echo (int)("2.50"*100);
echo "\n";
echo "2.55"*100;
echo "\n";
echo (int)("2.55"*100);
echo "\n";
echo (int)("230");
?>


Expected result:
----------------
230
230
299

250
250
255

230

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