Interesting...I think it could be a problem.  You'll either lose precision
(assuming that it really has that many significant digits), or you'll need
to store it in some other format (text, or a big number library).

If it wasn't apparent from googling (and it wasn't during the 5 min or so
that I did...maybe some more is warranted) then I'd recommend looking at
some known output, and reverse engineering.  I'll have to see if I have
anything that will produce decimal values...Where are you getting them?
