I also would be interested in this. I have heard of a program that
significantly increases Excels capabilities beyond the 15 or 16 significant
digits. Has anyone used these and had positive results? It was some time ago
when I first heard of them, about the time this post originated.

Thanks

have read Tushar Mehta's explanation of the problem, but need advice on which
is more accurate.
