places) get rounded down by one after running intval() on the result.

echo intval(70.74 * 100);
// testing for all numbers between 0 and 10 that do not hold the same
value after type change
for ($j = 0.00; $j < 10.0; $j = $j + 0.01) {
$i = ($j);
if (strval(intval($i * 100)) != strval(($i * 100))) {
echo $i . ': ' . intval($i*100) . ' | ' . ($i * 100) . '<br />';
}
}
?>
Expected result:
----------------
Expected value after evaluation: 7047
Actual result:
--------------
Actual value after evaluation: 7073
