Umm, floating point gives dynamic range.  It generally reduces precision.

The next question that comes to mind is what sort of communication channel 
are you getting your numbers through and  what sort of update rate so you need?

BTW, anyone else completely missing messages?  I've sent out at least one 
message that wasn't echoed back within 24 hrs and checking Yahoo's site I 
see others I haven't received.  I'm trying to figure out where they are 
getting swallowed.
