Common Lisp allows four float types -- short, single, double, and long.
These might or might not coincide. Maxima generally prefers doubles but
if there were other types in some formulas, the user might see some non-
double result -- I'm guessing that's the case here.

Maxima also has a variable-precision software float called a bigfloat,
which is not a CL type.
