Numerical is a bit tricky - you need to understand how many bits of
accuracy are retained by your calculation which in turn requires you
to understand what it is that you are modeling.

One approach, though [that often will work - not always, and it's
interesting to think about the failure modes] is to perform the
calculation twice, once using a higher precision version of the
calculation, and recognizing when the lower precision variant starts
losing accuracy by saying watching how it deviates from the higher
precision variant (and stopping there).
