Please take a look at following example:
<?php
echo ceil(83.47 * 100 * 31);
echo ceil(83.47 * 31 * 100);
?>

 For both for PHP 4.2.3 and 4.3.0 RC2, it gives me this result:
258757
258758

 which is definitly breaks mathematical rules. Correct result should be 258757.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Read up on the floating point type in the manual.
