How do I get JavaScript to show 2 decimal places, with two trailing zeros?

Question

I've managed to get JavaScript to round to 2 places using:
Math.round(x*100)/100
However if x = 6 it displays as '6' rather than '6.00' which I want.

Answer 1

Javascript has a built in method to do this on the Number object:

var x = new Number(25);
document.write(x.toFixed(2));

Answer 2

Js Round To 2 Decimal

Answer 3

First, I have never programmed with JavaScript.

However, if you always expect two trailing zeros, then I would try to display the 6 as a string and simply concatenate ".00" to the end.

Without more information about your program, there's no way to tell if this solution would be sufficient. Also, having zero experience with JavaScript, I'm not even 100% sure that it's possible.

Answer 4

The simplest solution would be to use a function to format your number. Change the name of the function to whatever suits you and edit the return statement to however you want to format the string.

function Currency( value) {
var temp = "" + (Math.round( value * 100));

return "$" + temp.slice(0,-2) + "." + temp.slice(-2);
}

alert( Currency(25));
