I will agree that it's much less obvious when you will get into trouble, since the numbers were of modest magnitude -- though still greater than sqrt(32768) which is a (very rough) indication of potential trouble.
this can be misleading: yes, you can add two rational<short>s together if all their nums and dens are smaller than 181 (a sufficient but not necessary condition); but to be able to add the results of two additions, the limit goes down to 13, then to 3, then to 1
In this case the obvious solution is rational<long>
with long calculating the limits this way you get 46340, 215, 14, 3, 1 -- even in a very simple program containing a few operators the arguments can only safely have the values zero and one... br, andras
