>A comment in the most general terms would be enough, if the nda allows it. And I don't want to include references to a specific person or company - I only want to know, and write, what use such a precision can have.

No problem! I would be happy to. I'm very curious myself. Pretty sure it has something to do with an accounting package.

> By the way, please do speed tests before commiting yourself to my class. You don't need to wait until I finish method .Divide() - you can start testing with .Add() and .Multiply().

> Try to find out how many numbers have to be thus processed - you can multiply two 100-digit numbers in a reasonable time (a fraction of a second), but to do thousands, or millions, of operations in a row, is quite a different situation.

Yes, I plan on dissecting the code thoroughly. Advanced math was never one of my strong points so again I appreciate having some code to work with.

> I estimate speed can be improved by a factor of about 10, compared with the current implementation, simply working on groups of digits in a row - but for me, this ain't #1 priority right now. The change should be quite simple in the case of the .Add() method. No change is required, of course, in the .Subtract() method.

I understand. Again thanks for the help!!!!
