hex

hex 
hexnum

Converts a hexadecimal string hexnum into its equivalent decimal value. If hexnum is omitted, it interprets $_ . The following code sets $number to 4,294,906,560:

$number = hex("ffff12c0");
To do the inverse function, use:
sprintf "%lx", $number;   # (That's a letter 'l', not a one.)
