I think this default would not be consistent with the general approach in
Maxima. In particular, if sum(..) can be done exactly, and the result then
converted to a bfloat, that is what I would expect the commands below to do.
Also you would have to consider what to do with (f(a)+sum (....)), bfloat.
How about this: use "nsum" instead of "sum" (Mathematica uses NSum vs
Or do this:
Simpsum:Levin, as a third option, other than true and false.
