Autoincrement of Hex value

[Diwakar Gana]

Dear All,

Can anybody tell me how to autoincrement the Hexa decimal value.

For Ex:

I am having the value FF0B in Result array and want increment it to FF0C. Now Result array should contain two values.

Hello Diwakar Gana!

I'm not 100% sure of the answer, but it looks like there is a related discussion over at perlmonks:

(I assume you mean 'increment' because I think 'autoincrement' refers to database table columns.) When you increment a hex string the result is an ordinary decimal number which you have to reformat as a hex string if that's what you want.

#!/usr/bin/perl
use strict;
use warnings;

#Create results array containing one value
my @results = ('FF0B');

#Add 1 to first element and format as hex string for second element
push @results, sprintf('%04X', hex($results[0]) + 1);

#Results array now contains FF0B, FF0C
print 'Results array now contains ', join(', ', @results), "\n";
