ANSI 3.1.2.5   The representations and sets of values of the various types of integers

Integers contain 32 bits (four bytes). Signed integers are represented in two’s-complement form. The most-significant bit holds the sign: 1 for negative, 0 for positive and zero. The values are listed below:

Type Minimum and Maximum
unsigned short 0 to 65535
signed short –32768 to 32767
unsigned long 0 to 4294967295
signed long –2147483648 to 2147483647
