Setting Number to 2 decimal places?

[loki421]

Hi all,

I'm trying to get an answer to 2 decimal places, i've got a number value that is returning too many decimals.

Here's the code:

private function getMath(event:Event):void
	{
		var myNumber:Number = new Number(input.text);
				
		var answer:Number = ((myNumber  /100) * 15) + (myNumber);
		answer.toFixed(2);
		var text:String = answer.toString();
		answerLabel.text = text;
	}

I'm using toFixed(2) but it's not working, does anyone know where this is going wrong? Any pointers/suggestions would be gratefully appreciated

Many thanks in advance all!

ok, i've realised that if i use a whole number as the input, then it works fine, but most likely the input will include 2 decimal places, is there a function that will allow the 'answer' to stay at 2 decimals event if the input contains decimals?

Can no one help wit this then? I've tried all sorts, Math.round, toPersicion, toFixed, but no matter what i use, if i input a decimal the function fails, i've tried looking for a report of a bug in Flex 3 for this, but no one else seems to be having this trouble....

Any suggestions?

Thanks all

Ha! Cracked it! For anyone else who's struggling withthis sort of thing, here's the answer:

private function CalculatePercentage(event:Event):void
{
	var myNumber:Number = new Number(price_input.text);
				
	var wholeNumber:Number = (myNumber * 100);
				
	var revertBack:Number = (wholeNumber  /10000);
				
	var GetPercentage:Number = (revertBack * 15);
				
	var percentageAnswer:Number = (GetPercentage + myNumber);
				
	var answer:Number = percentageAnswer;
				
	var display:String = answer.toFixed(2);// fixing to 2 decimals
	var text:String = display.toString();
	withPercentageprice.text = text;
}

Anyway, hope this helps someone

I've had that problem as well, but chose to use one of the controls:

  
<mx:CurrencyFormatter id="Price" 
	precision="0"
	rounding="none"
	decimalSeparatorTo="."
	thousandsSeparatorTo=","
	useThousandsSeparator="true"
	useNegativeSign="true"
	currencySymbol="$"
	alignSymbol="left"/>

Then I use that like this:

public function assignOutputVariables():void {
	// above columns - final results
	var tempFormat:Number;
	tempFormat = FSP.getFinalResults();
	resultPotentialResultsData.data = Price.format(tempFormat);
	assignFinalResultText();
...
}

Just an idea.

Yeah i did try that one, but for some reason when it gave me the 'answer' it included 2 decimals! ie: 245.674345.87545, wierd hey?

I assumed that it must have been because i was inputting decimals, and therefore outputting them too???

But with the code i posted i can input with decimals and still get only 2 decimal places returned, whatever you prefer i suppose

Thanks though
