Calculation blank instead of 0

[NatalieSlayden]

I have a integer field where I calculate a percent based on two other fields. If they enter zero for both, the percent is blank rather than displaying as 0. Is there any work around for this? 

(0/0)*100 = Blank 

instead of 

(0/0)*100 = 0

That is because you cannot divide by 0 in math.  Add an if statement that should work.  Like if(denominator is 0, 0 , else do the calc).

Hope that helps.
