The representations and sets of values of the various types of integers (§3.1.2.5)
Short integers contain 16 bits (two bytes). Long 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 |
