Hi. I was just wondering how I could get the output of this bit of
Javascript to round up to two decimal places. My code is below. Thank
you.

"<script language="JavaScript">

<!--

var price1 = 2.99
var price2 = 13.98
var price3 = 8.95
var price4 = 1.99

var oprice = price1 + price2 + price3 + price4

document.write(oprice)
//-->

</script>"

The output I'm getting is 27.909999999999996

Thanks again.

In general, you want to round to nearest, not round up.

Before posting, you should read the newsgroup and its FAQ; your
situation is amply covered therein.

Omit first ". Attribute deprecated.

Omit ".

Yes.

If you want an answer exact in pence, then you can work in pence.
Integers up to 2^53 are held exactly, but most decimal fractions are
not.
