In my opinion it is the better than yielding True. 0/0 doesn't make
sense. So it can't be compared to anything else which doesn't make
sense. 

Whether == should yield False at all is another matter. It may be better
to yield some kind of bottom (undefined?), but then compatibility with
IEEE 754 might be an issue, hence using external libraries like BLAS,
gmp, ...
