Javascript toFixed Not Rounding

Question

I'm using javascript to bind to some checkboxes, and the `toFixed(2)` is not rounding up. Any ideas why it's not rounding? For instance, if the number is `859.385` it's only displaying `859.38` instead of `859.39`. I've also read that the `toFixed` can round differently depending on which browser you are using, anyone know of a way around this so that my javascript calculations match my php calculations? ``` var standardprice = parseFloat($('#hsprice_'+this.id.split('_')[1]).val()); var price = parseFloat($('#hprice_'+this.id.split('_')[1]).val()); var discount = parseFloat($('#hdiscount_'+this.id.split('_')[1]).val()); var deposit = parseFloat($('#hdeposit_'+this.id.split('_')[1]).val()); var currSprice = parseFloat($('#hTotalSprice').val()); var currPrice = parseFloat($('#hTotalPrice').val()); var currDiscount = parseFloat($('#hTotalDiscount').val()); var currDeposit = parseFloat($('#hTotalDeposit').val()); currSprice += standardprice; currPrice += price; currDiscount += discount; c…

Accepted Answer

I have yet to find a number that toFixed10 does wrong. Can anybody else?

Thanks to `blg` and his answer which pointed me to Mozilla's toFixed10() method.

Using that I came up with this short one liner, which indeed covers all cases mentioned here...

```
function toFixed( num, precision ) {
    return (+(Math.round(+(num + 'e' + precision)) + 'e' + -precision)).toFixed(precision);
}
```
