Re: I need Hex conversion, not!

This works, but it will give you a slight performance hit. Unless you're doing serious number crunching it'll probably be acceptable...

use strict;
use warnings;

sub hexnum {
    package HexNum;
    use base 'Math::BigInt';
    use overload q[""] => 'as_hex';
    __PACKAGE__->new(@_);
}

my $var = hexnum 0x2F;
$var += 3;
$var += hexnum 0x02;

print "$var\n";

Wow, that is cool. Btw, is there a way to ignore 0x prefix without substr, or anything ?	[reply]
