Hi,
8. [...] Saying 0**0 is undefined seems reasonable, but why 0**y? I agree on 0**y being 0 (not undefined), but why should 0**0 be undefined? x**0 := 1, by convention.
I'm not familiar with that convention. So far as I'm aware, the x**0=1 vs 0**y=0 conflict leads to 0**0 being best handled as undefined. That is, I've not seen any arguments supporting either solution as somehow more natural or more helpful in mathematics. </source-please> -- Live well, ~wren
