note 24271 added to language.types.float

I found the following function useful. I'd obviously be interested to know if I've missed something obvious. function div($a, $b) { // we can't divide 0, or divide by 0 if ($a == "0" || $b == "0") { // return an error return "Sorry, the input is not valid."; } // divide a by b, more accurately than php does otherwise return ($a * $b) / ($b * $b); } e.g. $test_num = '19.95'; echo 'The original number: ' . $test_num; echo 'Div by 10 and use number_format: ' . number_format($test_num / 10,"2"); // equals 1.99, not 2 echo 'As above but with the new function: ' . number_format(div("$test_num", "10"),"2"); // now we get 2 -- http://www.php.net/manual/en/language.types.float.php http://master.php.net/manage/user-notes.php?action=edit+24271 http://master.php.net/manage/user-notes.php?action=delete+24271 http://master.php.net/manage/user-notes.php?action=reject+24271
