Sounds straightforward for integer types, and there's a pointer type
somewhere as well. What about floats? From the manual:

"On most but not all systems, :float and :double represent a Lisp
single-float and double-float, respectively. It is not so useful to
consider the relationship between Lisp types and C types as
isomorphic, as simply to recognize the relationship, and relative
precision, among each respective category."

I don't remember what the implications are.

Why not let the user decide that?
