As I indicated earlier, I believe that expecting Intervals to work 
for floats is misguided, so I agree with the philosophy of making a 
separate subclass for floats.

However, I would like to point out that the code that I originally 
submitted, as fixed by Dave Smith and others, does work just fine for 
fractions, where rounding errors and approximations are not a 
problem.  So the class comment described above is rather more 
restrictive than necessary.
