Thanks for getting back to me., I really appreciate it
Using coerce though I'm already casting it to a float on the lisp side...I was wondering if I can cast a 4 to a float with CFFI and have the output be a 4.0f0 like it works in C...without doing anything on the Lisp side

This is the way I thought you did it but I'm running this and it's not working:
(with-foreign-object (float :float) (setf float 6) (type-of float))
>(INTEGER 0 4611686018427387903)
The output says it is an integer
I tried this:
(with-foreign-object (float :float) (setf (mem-ref float :float) 4) (type-of (mem-ref float :float)))
(with-foreign-object (float :float) (setf (mem-ref float :float) (coerce 4 'single-float))
(mem-ref float :float))
or use the syntax 4.0s0 for a literal single-float(4.0d0 is a literal double in comparison).
