Isn't this true only if the representation is in the form n/m for n,m
belonging to [int_type_min,int_type_max]? But if you take out the
non-decimal part, ie. factor every number as k+n/m, then n/m is always
between 0 and 1, and the triplet (k,n,m) adequately represents rational
numbers over a very large range. If still insufficient, you could probably
factor it into a quadruplet (k,j,n,m) where all are ints and describe a
number of the form k.10^j +n/m.

Then again, maybe this is not at all what you meant by the above statement
