Well you could return -1, 99 or any arbitrary integer for that matter; just that it doesn't make sense to do that from a pure maths perspective. Mathematicians have spent centuries trying to make number systems consistent. The invention (or discovery**) of "i", the square-root of minus-one, was a major major break-through. In similar vein, it's nice if the type systems we use for programming follow from a consistent set of axioms. ;-) (**Is mathematics invention or discovery?) <JJ/>
