re: converting decimal to hex and oct - 
use warnings;
use strict;
print "Please input a hex no. to convert to dec. :";
chomp (my $value = <STDIN>);
print hex("$value"), "\n";

Just replace hex( ) with oct( ) for oct. For binary there is no bin( ), I was struggling with the same problem recently -

http://perlmonks.org/index.pl?node_id=591504

should find some answers there. PS - can someone please tell me the tags to make urls clickable in a post? Ta

Edit, sorry - just spotted that I got the conversion backwards in the code

    Hi thevoid,

    If you read the documentation, you'll see that oct is capable of conversion from binary.  It just requires putting a leading '0b' in front of the number.

    For example: 

    use strict;
use warnings;

my $value = "0b101010";
printf "$value is %d decimal\n", oct($value);

    Not too long ago, I even wrote a submission about it, in which I admitted that I didn't know about this additional functionality of oct until much later in my Perl education.

    As for your other question, to make links clickable, you can do this:  [id://591504], which will appear like "Bitwise operators" in the rendered page.

    See Writeup Formatting Tips and Perl Monks Approved HTML tags for more information.

    Update:  Fixed a transcription typo.

    s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
