Thank you, I would like to have a look at the code if you don't mind.

A follow up: In the program I'm writing I'm having the computer do a numerical integration of the type of function listed above. My method right now is to do a simple Riemann sum using a For Next loop. I find I can get better accuracy by using more segments so that for instance I could have the loop run 2.1 billion times and sum up the tiny areas. This takes 33 minutes to do an integration that I can do in my head in 30 sec. Is there a faster mechanism for running the same kind of Riemann sum the same number of times but in much less time?

Thanks - Eric
