var cf:CurrencyFormatter = new CurrencyFormatter( "en_US" );
this.payroll.value = this.payrollOut;
cf.format( this.payrollOut.text );  //??

Answer 1

A better alternative for currency formatting is to use the Adobe class flash.globalization.CurrencyFormatter

public static function getDollars(value:Number):String{

        var targetFormatter:CurrencyFormatter = new CurrencyFormatter("en-US");
        return targetFormatter.format(value, true);

    }

This class is very flexible, allowing to you customize the currency appearance for locale.

Answer 2

Hey there I hope this helps,

myTextField1.text = formatCost(String(4813.134),2,"$",0);// result: $ 4,813.13

The function is pretty simple, we call the function formatCost()

If you just wish to format it to 0 decimals, formatCost(value as string,0)
If you need a currency add that in as the 3rd parameter.
If you need the symbol to appear behind the number, have the position set to 1
So...

formatCost(String(8/35*100),1,"%",1);// will give "22.9 %"

if wanted, you can tack on more to the formula so that the 5th variable could be the spacer, so that you could change it from a "," to a "." (for french) or as a space " "

public function formatCost(v:String, 
           decimal_places:int = 2, 
           currency_symbol:String = "", 
           placement:int = 0){
        v = String(Number(v).toFixed(decimal_places));
        var result:String = new String();
        if(decimal_places == 0){
        }else{
            result = v.substr(-1-decimal_places);
            v = v.substr(0, v.length-1-decimal_places);
        }
        while( v.length > 3 ){
            result = "," + v.substr(-3) + result;
            v = v.substr(0, v.length-3);
        }
        if(v.length > 0){
            if(placement == 0){
                result = currency_symbol + " " + v + result;
            }else if(placement == 1){
                result = v + result + " " + currency_symbol;
            }else{
                result = v + result;
            }
        }
        return result;
    }//closes formatCost

The issue is that you are not paying attention to the variable types.

this.payrollOut -- is a textfield

this.payrollOut.text -- is the text contained in that textfield

this.payroll.value cannot be assigned a textfield or a text value

So you must convert to the type that it is expecting -- in this case a Number.

this.payroll.value = Number(this.payrollOut.text);

cf.format is expecting a Number value as well, and will return a String.

an example of usage might be :

var payrollAmount:Number = 400;
var payrollCurrencyAmount:String = cf.format(payrollAmount);

There are other issues with the code that I see -- payrollOut has no value - so it's still not going to function as expected, but this solves the immediate problem.
