Thanks for the explanation.
In my case, the values are $0.00 so exact is a necessity. I'll try "ROUND" and see if it solves my problem. I would expect I can avoid teh middle man and have the value in C2 calculated as =ROUND(R7*J2+J5,2). Correct?

As for the values, #1 is Pi, #4 is 2squared, number 2 . . . I'm not sure. I think it's 'e' but that's an educated guess. @3? No idea. Doesn't look familiar.
