I want to convert negative number to its positive equivalent. $num = -40; printf("Unsigned value is %u", $num); output is: Unsigned value is 4294967256 I have checked the manpages and %u seems the right format. Pls advise. -- roger --------------------------------------------------- Sign Up for free Email at http://ureg.home.net.my/ --------------------------------------------------- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
