Sorry for causing such a mess. The other day, I tried several things and
didn't re-try them after restarting Maxima. This works for me.
(C1) display2d : false$
(C2) tellsimpafter(del(p),0)$
(C3) ratsimp(diff(u*v^p));
(D3) (p*u*v^p*DEL(v)+v^(p+1)*DEL(u))/v
The ratsimp in (C3) is needed to do del(p) => 0.

P.S.
Maybe there should be an alternative float function that (i) fails if the
expression doesn't evaluate to a float and (ii) uses the native complex
numbers from Lisp.
