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

Subject: 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.
