Enumeration

CFNumberType

Flags used by CFNumber to indicate the data type of a value.

Declaration

enum CFNumberType : CFIndex

Overview

The type specified in the call to CFNumberCreate(_:_:_:) is not necessarily preserved when creating a new CFNumber object. A CFNumber object uses whatever internal storage type the creation function deems appropriate. Use the CFNumberGetType(_:) function to find out what type the CFNumber object used to store your value.
