Constants And Internal Representation 

ANSI C acknowledges that the size and numeric range of the basic data types (and their various permutations) are implementation-specific and usually derive from the architecture of the host computer. For CodeGear C++, the target platform is the IBM PC family (and compatibles), so the architecture of the Intel 80x86 and the Pentium family of microprocessors governs the choices of internal representations for the various data types.
The following tables list the sizes and resulting ranges of the data types. Internal representation of numerical types shows how these types are represented internally.
