<?
   $bytes=2640947434103;
   $a=floor($bytes/1024);
?>

This fails. If you substitute floor with either ciel or round it works fine. The bug is also in php 3.0.12.

Only module added is mysql.

No changes is made to php.ini

This should be fixed for 4.0.1pl2. Please reopen if you still have this bug.

this bug still exists in cvs
it also happens to ceil(), despite what the user says

it's because ceil and floor return longs
they need to return doubles so they can handle larger values - this is what the C library's doing anyway

does anyone object to this change?
