This function will round numbers to two decimal places, and ensure that the returned value has two decimal places. For example 12.006 will return 12.01, .3 will return 0.30, and 5 will return 5.00

```
function CurrencyFormatted(amount) {
var i = parseFloat(amount);
if(isNaN(i)) { i = 0.00; }
var minus = '';
if(i < 0) { minus = '-'; }
i = Math.abs(i);
i = parseInt((i + .005) * 100);
i = i / 100;
s = new String(i);
if(s.indexOf('.') < 0) { s += '.00'; }
if(s.indexOf('.') == (s.length - 2)) { s += '0'; }
s = minus + s;
return s;
}
```

Hey, here’s myself from the future. I re-gazed upon this, and further improved things:

`function currency(n){n=parseFloat(n);return isNaN(n)?false:n.toFixed(2);}`

Is it a css trick?

Hi all!!

Is there any way to add comma while typing number? and we can edit all of number.

Ex: 123,456,555, we can edit number 1 –> 6

Thanks

On keyup check the length of the field. If it is greater than 4 and contains no period, add a comma after every 3rd number from the right. When a period is encountered, set a flag to stop the formatting.

// with comma for thousands

function format_currency(amount){

var i = parseFloat(amount);

if(isNaN(i)) { i = 0.00; }

var minus = ”;

if(i < 0) { minus = ‘-‘; }

i = Math.abs(i);

i = parseInt((i + .005) * 100);

i = i / 100;

s = Number(i).toLocaleString(‘en’);

if(s.indexOf(‘.’) < 0) { s += ‘.00’; }

if(s.indexOf(‘.’) == (s.length – 2)) { s += ‘0’; }

s = minus + s;

return s

}

The website’s name is css-tricks but you give a Java solution?

He didn’t give a java solution, he gave a javascript solution. ;)

i want to put auto price changer to my website

please review my website: http://www.phonegallery.in

Personally, I prefer to use currencyFormatter.js (https://osrec.github.io/currencyFormatter.js/). Cross browser and light. Can format numbers according to currency and/or locales:

function formateIndianCurrency(rupees) {

}

as of 2018, this functionality is built in to

`Number.toLocaleString`

There is an additional option

`currencyDisplay`

which defaults to`symbol`

and shows the appropriate symbol for the`currency`

.
