in thread How to increment a MAC Address?

HEX to DEC
You mean convert a hex string to a number. It's not a decimal number until you print it for output. I don't see any place that you are stringifying it.

Re^4: How to increment a MAC Address?

    I did this: 
      # clear separators to obtain a hex string
    $mac =~ s/://g;
  # convert hex string into a dec number
    my $dec = hex($mac);
  # revert into a hex string 
    $mac = sprintf("%012x", $dec+$add);

    I don't see error here. I think it's used by context...

      My argument is with the word "dec" there. It's not decimal. It's just a number. In fact, it's more binary than it is decimal. {grin}

      The "hex" operator interprets a hex string or an octal string, converting them to a number. A number is an abstraction, without a numeric base, until it gets converted to a string again.

      Thus, you never really have a "decimal" number there. Just a number. Because you never printed it out.
