Format Int to String Function?

[Qugh]

Anyone have a good idea how I should format a long integer into string format with commas? I don't know if there's a built-in func for this, but I haven't found it.

raw int: 2000000
parsed string: 2,000,000

u should use. Number.toString() .. than String.substr() for parsing ;) :mu:

Thanks a lot for the input! I ended up writing a custom function to do the task properly. Here it is (in case anyone else needs to use it):


//function to parse dollars to even numbers
function formatDollar(pVar)
{

var parsedString = "";
//find where to start adding the comma (out of every 3)

skipChars = String(pVar).length % 3;
if( skipChars==0 ){ skipChars = 3; }

//split into array
strArray = String(pVar).split("");

//how soon to add comma
var recurKey = skipChars;
//loop through string to add comma
for( i=0; i<strArray.length; i++ )
{

parsedString = parsedString + strArray[i]

//determine if comma is inputted
recurKey--;
if( recurKey < 1 && i<strArray.length-1 )
{
parsedString = parsedString + ",";
recurKey = 3;
};

}
return "$ " + parsedString;
}

Actionscript 3.0's regular expressions will be handy for this sort of task, should reduce your function right down.

Hi Qugh,

I have a quick question for you on the code posted for currency formatting.

I am tring to get a set of dynamic txt boxes to show the final calculations in the currency format. When I changed the "var parsedString" to the var "" that I am using, nothing happens. Can you point me in the right direction on what I am doing wrong.

Thanks,
