Help with 2byte representation Can't Post
Hi

I have a hex value as input = FF28. Its a 2 byte integer.
If i convert it to decimal using a calculator the decimal value -216

How can i do that conversion in Perl . I have tried using a few combinations with unpack but none of them gives me -216

Thanks in advance

Got it

Code
use strict; 
my $An = unpack ('s',pack ('S',hex('ff28'))); 
print "A= $An\n"; 
 
C:\Perl64\OnesComplement>perl Ones.pl 
A= -216
