Re: stripping negative number

unsigned does not equal absolute value. $num = -40; print "Num: $num\n"; $num = abs($num); print "ABS: $num\n"; will display: Num: -40 ABS: 40 http://us2.php.net/manual/en/function.abs.php Justin ----- Original Message ----- From: "Roger Thomas" <sniper@home.net.my> To: <php-general@lists.php.net> Sent: Thursday, December 23, 2004 1:18 AM Subject: [PHP] stripping negative number

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
