Round & Limit Decimal Places in Calculated Result 1

[megp]

I use the following script to calculate the total amount due based on the amount ("invoice") entered in the form ("pay"). All works as needed, except that I need to be able to limit the results to two decimal places, preferably rounded as needed. What am I missing?

Thank you,
Meghan

<script language="JavaScript">
function doTotals()
{
var x = document.forms['pay'].elements['invoice'].value;
var z = ((x*1.029)+(0.3))
document.forms['pay'].elements['amount'].value = z;
}
</script>

Missing this:

var z = ((x*1.029)+(0.3))[!].toFixed(2)[/!];

<.

Perfect! Thank you!

If you also want this rounded, preferrably down, you can do this:

var z = Math.floor((x*1.029)+(0.3) * 100) / 100;

<.
