That's an excellent suggestion, which I hadn't considered-- as long as you do the multiplication first, it should work fine.
Unfortunately, my real problem is a little more complicated, so I can't do it that way. I'll probably just use MathUtil, but I'll try to keep your suggestion in mind-- it may come in handy for something later. --Paul On 8/8/06, Gonzalo Diethelm <[EMAIL PROTECTED]> wrote:
