Rounding of number to 2 decimal places or more..
Hi there.. how do i round off a number to 2 decimal places?
This code taken from www.w3schools.com only round the number to a whole number.
<html>
<body>

<script type="text/vbscript">
i = 48.66776677
j = 48.999
document.write(Round(i))
document.write("<br />")
document.write(Round(j))
</script>

</body>
</html>

Add the number of decimal places you wish to round to the end of the Round, as follows:

Quote:
document.write(Round(i,#))


Where # is the number of places to round to.

Try changing document.write to response.write

I believe document.write is a javascript function not a vbscript function.

<%

r1=Trim(request.form("r1"))
r2=Trim(request.form("r2"))
r3=Trim(request.form("r3"))
I=Trim(request.form("I"))
urans=Trim(request.form("Answer1"))
result= Round(CLng(r3)*CLng(I)/(CLng(r2)+CLng(r3)))

if (CStr(result) = CStr(urans)) then
response.write " the right value is " & result & " ,so you are right"
elseif (CStr(result) <> CStr(urans)) then
response.write " the right value is " & result & " ,so you are wrong"
End if
%>


this is my code.. how do i change this line to make it 2 decimal places.. so far it rounds off to a whole number
result= Round(CLng(r3)*CLng(I)/(CLng(r2)+CLng(r3)))
