Suppose $foo=9999999 and $bar=10000000. Then since $foo<$bar, you would want int($foo/$bar) to return 0, but 9999999/10000000+0.0000001=1.000000000, so (int)($foo / $bar + 0.0000001)=1. It's not generally a good idea to rely on truncated floats for integer divisions. -- http://www.php.net/manual/en/language.operators.arithmetic.php http://master.php.net/manage/user-notes.php?action=edit+24913 http://master.php.net/manage/user-notes.php?action=delete+24913 http://master.php.net/manage/user-notes.php?action=reject+24913
