not a php expert but have filed this bug report re validating is_numeric('3e0'); http://bugs.php.net/bug.php?id=32943

Yeah I read that report... and as it says you're using Euler's notation.

Now tried function isnumeric($n) { if (ereg("^[0-9]{1,50}.?[0-9]{0,50}$", $n)) {

if (preg_match('/^[0-9]+\.?[0-9]+$/'), $n) {

     return true;
} else {
     return false;
} } and that doent seem to work either.. any ideas.. need to validate anything without 0-9 and a dot within tia Pete
