Seminumerical Algorithms has a few problems on "floating slash", ie a
representation of numbers where the total memory allocated to a
fraction is fixed, but the amounts allocated to numerator and
denominator are variable.  I don't know if it has ever been tried in
practice, though.  And of course any reasonable fixed size would have
very limited ability to express very large or very small magnitudes.
