Another "how to round" question

I have read the rounding forums but am still unsure how to incorporate it into my code.

function calculateResult(){
var pcintX = document.form1.x.value;
var pcintY = document.form1.y.value;
var pcintZ = ((pcintX * pcintX)*90.69)/(pcintY * pcintY);
document.form1.z.value = pcintZ;
return false;
}

I need the calculation to round the pcintZ value to 2 decimal places.

Any help on how I could do this?

Thank you

Rounding something to two digits is the same as multiply it by 100, rounding it to an integer, then dividing it by 100 again. Like this:

pcintZ = Math.round(pcintZ * 100) / 100;

If you want it to always display two decimals (instead of dropping ending zeroes), you can have a look in the FAQ. You can find a function for doing that in there.

Great thank you! - Problem solved.
