This is actually not a bug, but a normal thing with floatingpoint
numbers. If you want to do precise calculating, use cents, or decrease
the precision in php.ini from 14 to something like 10.

This was submitted by one of our head developers. We're using
PHP/MySQL to build our customer relationship software, and this scares
me.

The numbers should add to 0. When I echo the result I get the below:
-5.6843418860808E-14.
<?
echo 241.20 + 169.23 - 410.43;
?>
