The value of the result is actually '3' after reducing, but I'm assuming that a division of a type Complex by a type Complex would assume a result of type Complex, regardless of the actual value. This is why I assumed that the result would be promoted, even if it's not actually necessary. > >Perhaps there could be a sort of 'try' for > >conversion that returns the best possible result? > > That's an interesting idea.

I have to subscribe to ANOTHER list?!?!? <<grumble>><<grumble>> Actually, maybe if I just post it with a note that I'm not subscribed :-). Grant M.
