Getting Commas In Numbers

Hi Everyone --

Having some trouble figuring out how to format a number so that commas appear after every third digit... you know, so basically, if I'm displaying a large number like 72,000,000, I don't want it to show up as "72000000". Right now the way this is set up, that's what happens, and I'd like to change that, but I'm somewhat of a beginner and have no idea how to go about it.

(By design, this is a counter that figures out how many seconds into the current year we are in, multiplies that number by 3, and then increments by 3 every second.)

I'll attach my code below. Any help would be greatly appreciated!

Here is some code that will do what you want. I got it from an older post on this same topic.

strSeperator = function(num,delimiter){//takes long number(or string) and incrementally inserts a character
sign = num<0 ? '-' : '';
num=Math.abs(num).toString();//convert Numbers to String
pos = (num.indexOf('.')==-1) ? num.length : num.indexOf('.');//var 'pos' is used to add a seperator at
while(pos>3){//while loop, starts at String right moves to left
pos-=3;//move left to next seperator point
n2=num.slice(pos,num.length);//get all characters after seperator point as new substring
n1=num.slice(0,pos);//get all characters before seperator point as new substring
num=n1+delimiter+n2;//combine before-substring + dilimiter + after-substring as new 'num' String
}
return sign+num;//return 'num' to where function is called
}

//example
myNum = 7625428765237;
myNumFormatted = strSeperator(myNum,".")
trace(myNumFormatted);

I could have made this a one-liner, but then it looks REALLY ugly ;)

Here's a simpler way figure the number of seconds:

//set variables
var views:Number = 3;
//get current time
var d = new Date();
//figure out start number
var num:Number = (d-new Date(d.getFullYear(),0,1))/1000;
var startSeconds = Math.floor(num * views);
