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.)
