As so often happens, after I sent my reply I re-read your post and I think I understand what you are getting at. One problem with my approach is that I am truncating the result down to the desired scale factor every time I create a new instance. This could result in a loss of precision if I chain a series of instances together in a calculation. I think that what you are suggesting avoids this problem. I will read your message again carefully. I think it will lead to a rethink of my approach. Thanks again Frank P.S. Despite my earlier reply to Paul, I have not abandoned the idea of using my Number class as opposed to the standard Decimal class. I did a simple test of creating two instances and adding them together, using both methods, and timing them. Decimal came out 6 times slower than Number. Is that important? Don't know, but it might be. -- http://mail.python.org/mailman/listinfo/python-list
