Tell you what, I'm gonna stop posting to the list within the 10
minutes after I first wake up. Then maybe I wouldn't have overlooked
CFNumberGetType. But the documentation for that function is very clear
that you cannot use this to do what the OP asked for:
"The type specified in the call to CFNumberCreate is not necessarily
preserved when a new CFNumber object is created—it uses whatever
internal storage type the creation function deems appropriate."
