It would be just too confusing to future readers if I tried to go back and removed my non-helpful posts so I guess I will leave them there.
I personally think they're germane and useful to the discussion; I already knew about the issue myself, but seeing it laid out makes me appreciate and understand it better; I am sure it will do the same for future people who view this thread.
To that end, I also wanted to post a link to this thread, since it hasn't been mentioned:
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1276236623
It won't solve any problems, but it should be mentioned.
I also seem to remember reading another thread recently where somebody mentioned a true double precision library...if I find it again, I will post it!
