Bug description: Rounding error when casting
Description:
------------
When rounding with int casting, it seems to screw it up on this weird
case. If you cast 230 to int, it will change to 229 in this one case.
Reproduce code:
---------------
$r = 2.3;
echo $r."<BR>";
$r = $r * 100.0;
echo $r."<BR>";
$r = (int)$r;
echo $r."<BR>";
$r = $r / 100.0;
echo $r;
Expected result:
----------------
2.3
230
230
2.3
Actual result:
--------------
2.3
230
229
2.29
