Margin Divisible by 5?

[Anonymous]

Hi,

I am looking to find a calculation that will tell me whether an item was sold at a margin divisible by five or not. i.e. ..., 35%, 40%, 45%, 50%, ... etc. I figured it would be simple using the MOD function. I tried each of the following

DivisibleBy5 = IF(MOD([Margin], 0.05) = 0, "Yes", "No")

DivisibleBy5 = IF(MOD([Margin] * 100, 5) = 0, "Yes", "No")

 Each give me an error saying "An argument of function 'MOD' has the wrong data type or the result is too large or too small". 

My [Margin] is a decimal number and classified as such. Any idea what's going wrong? Any other ways to get the result I'm looking for?

Thanks, 
Ryan
