force2 decimal flash

• anayafx

  so im trying to get a dynamic text box to display only 2 decimals to display a price for a shopping cart
  you know:
  $0.00
  (displaying $ cents)

  when i do calculations i get numbers like 4.23425.
  how can i get them down to 2 decimals? i.e. 4.23

  function roundDec(num, places)
  {
  var p = "1";
  for (var i = 0; i < places; i ++) p += "0";
  p = Number(p);
  return Math.round(num * p)/p;
  }

  so do:
  myTextField.text = '$" + roundDec( 12.4567, 2 );

  would display $12.46
