I would check out the modulus operator (%); something like the following: $zeros = 0; // Ensure the number is an integer (if // you already know this, you can skip // this step). // NOTE: no overflow checking! while ($number != (int) $number) { $zeros--; $number *= 10; } // Look for trailing 0s while(($number % 10) == 0) { $number /= 10; $zeros++; } -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
