Formatting percent and dealing with division by zero problems

[Bill]

I have some values that I want to display as percent, such as the
retail price/wholesale price. In some instances, the wholesale price
is zero, so I get a division by zero error.

What can I do to avoid this?

Also, how can I get this to only show two decimals, instead of it
going .##### the way it does. I want it to look like .45%

Thanks a million,

Bill

if wholesaleprice > 0 then
response.write retailprice / wholesaleprice
else
response.write retailprice / retailprice
end if

Look at the formatnumber / formatpercent functions.

[dlbjr]

function Divide(strNom,strDenom,intDecimal)
Divide = 0
if IsNumeric(strNom) and IsNumeric(strDenom) then
if CDbl(strNom) > 0 and CDbl(strDenom) > 0 then
if IsNumeric(intDecimal) then
intDecimal = FormatNumber(CDbl(Abs(intDecimal)),0)
else
intDecimal = 2
end if
Divide = FormatNumber(CDbl(strNom) / CDbl(strDenom),intDecimal)
end if
end if
end function

'Example
Response.Write Divide(234,321,3)

Thank you for the function! For your own knowlede, in order to calculate
the percent markdown from a retail price, the correct way to do it is
(denominator - numerator)/denominator

so if we're selling a $10 dollar item for $9, and we want to show that
is a 10% discount, it would be
(10-9)/10
1/10 = 10%

Your equation simply showed the numerator over the denominator.

By the way, this isn't adding the percent sign, I have to concatenate it
manually. Any way for that formatting to happen with a function?

Thanks again,

Bill

Have you looked at the formatpercent function?
