I think, before using floating point on a system without LOTS of extra
precision (ie 64/80 bit "doubles" on PCs), you might also need to
review your numerical analysis textbooks so that you have a good
understanding of how errors collect, even with floating point...

I remember what a rude awakening it was when APL on my DEC wouldn't do
my physics homework.  It didn't have the range to do 1/hbar^2.  Grr.
