Re: [office-formula] Constraints and infix ^

0^0 is actually an interesting (and complicated) case.

Traditional mathematics says that it should be "1" by definition, but "0" is a conceptually plausible answer.   An Error is obviously plausible, because of this.  Yet "^" is a function, and thus, should return at most one answer. 

The question is, what should the _specification_ say?
