I found some code here on how to translate between binary and decimal code: 

sub dec2bin {
    my $str = unpack("B32", pack("N", shift));
    $str =~ s/^0+(?=\d)//;   # otherwise you'll get leading zeros
    return $str;
}

sub bin2dec {
    return unpack("N", pack("B32", substr("0" x 32 . shift, -32)));
}

The problem I am having is that I get the EXACT same binary out no matter what I put into the dec2bin function. The same goes the other way around. I am using Perl on a Win32 system.

The reason I want to be able to do this is because I am trying to build a binary matrix of every combination depending on the number of columns that the user supplies. How I intend to figure this is out is by taking a "1" for every column thus a 3 column matrix will have a binary "111". Take this number and translate it into decimal will give you the number of rows needed for the matrix. Then I will count from 0 to 7 (for a 3 column matrix). Then transate the row number into binary and that will give me the 1's and 0's for each row in column order. Therefore, I need a reliable way of translating from binary to decimal and back again.

Thanks for any replies on this!
