~ Integral's ~

Ranges based on Microsoft's default C++
You can double the size of any integral by preceding the type with the "unsigned" keyword, but in doing so the sign is always ignored.
- ( e.g. The range of a 16 bit, unsigned int is [0, +65,536] )
char
- contains members of the basic execution character set. ( Microsoft C++ has a default of ASCII )
int
- To size an integer precede w/ "__intb' where b = the bit size.
  - __int8
    - Range [-128 , + 127
  - __int16
    - Range [-32,768 , +32768]
    - Aka short, short int, signed short int
  - __int32
    - Range [-2,147,483,648 , +2,147,483,648]
    - Aka int, signed int
  - __int64
    - Range [-9,223,372,036,854,775,808 , +9,223,372,036,854,775,808]
    - Aka long, long int, signed long int

~ Floating Point ~

float
- Range [3.4e +/-38] (for both +/-)
- Smallest floating point #
- 4 bytes
double
- Range [1.7e +/- 308] (for both +/-)
- >= float
- 8 bytes
long double
- >= double
- In Microsoft's C++ double & long double have identical representation.
- Considered a separate type from double.

~ Data Models ~

32 bit systems
- LP32 or 2/4/4 (int is 16-bit, long & pointers are 32 bits)
  - Win16 API
- ILP32 or 4/4/4 (int, long & pointer are 32 bits)
  - Win32 API
  - Unix & Unix-like systems (Linux, Mac OS X)
64 bit systems
- LLP64 or 4/4/8 (int & long are 32 bits, pointer is 64 bits)
  - Win64 API
- LP64 or 4/8/8 (int is 32 bits, long & pointer are 64 bits)
  - Unix & Unix-like systems (Linux, Mac OS X)
