how to represend a hex-string in perl ex: aa 01

Hi Aagal,

I'm not sure what you are asking here. Do you want to know how to represent a string like aa01 as a hexadecimal number in your code?

my $number = 0xaa01;

Or did you want to print the number in hexadecimal form?

#! /usr/bin/perl
use strict;
my $number = 0xaa01;
print "Number (in decimal form) is $number\n";
print "Number (as hex digits only) is ", sprintf("%1x",$number), "\n";
print "Number (as a C-style hex number) is ", sprintf("0x%1x",$number), "\n";
 

which prints

Number (in decimal form) is 43521
Number (as hex digits only) is aa01
Number (as a C-style hex number) is 0xaa01

Or was there something else you had in mind?

Best Regards,
Paul
