comma(,) after 3 digits

[VenkatBaddi]

i trying ot add comma(,) after 3 digits to my result value.

but result first time is good, and 2nd time is result changed (not correct result value)

my code:

var reg:RegExp = /\d\d\d$/g;
var a:Array = new Array();
var res:String ='';
var dnSpeeds:String;
  dnSpeeds = e.params.bandWidth;
  downSpeeds.text = dnSpeeds + " Kbps";
  downTest();
 while (dnSpeeds.length > 3){
          a.push(','+dnSpeeds.match(reg));
          dnSpeeds = dnSpeeds.replace(reg,'');
          }
          for (var i:int = a.length; i > 0; i--){
          res = res+a[i-1];
          }
          res = dnSpeeds+res;
          trace(res);
function downTest()
{
if (Number(dnSpeeds) >= 512)
          {
  Pass.visible = true;
  Fail.visible = false;
          }
else{
  Pass.visible = false;
  Fail.visible = true;
          }
}

I used this function, I found somewhere that I can not remember

function addCommasToNumber(number:Number):String

{

    var negNum:String = "";

    if (number<0)

    {

        negNum = "-";

        number = Math.abs(number);

    }

    var num:String = String(number);

    var results:Array = num.split(/\./);

    num = results[0];

    if (num.length > 3)

    {

        var mod:Number = num.length % 3;

        var output:String = num.substr(0,mod);

        for (var i:Number = mod; i<num.length; i += 3)

        {

            output += ((mod == 0 && i == 0) ? "" : ",")+num.substr(i, 3);

        }

        if (results.length > 1)

        {

            if (results[1].length == 1)

            {

                return negNum+output+"."+results[1]+"0";

            }

            else

            {

                return negNum+output+"."+results[1];

            }

        }

        else

        {

            return negNum+output;

        }

    }

    if (results.length > 1)

    {

        if (results[1].length == 1)

        {

            return negNum+num+"."+results[1]+"0";

        }

        else

        {

            return negNum+num+"."+results[1];

        }

    }

    else

    {

        return negNum+num;

    }

}
