Integer types

The format of an integer-type variable depends on its minimum and maximum bounds.

· If both bounds are within the range -128..127 (Shortint), the variable is stored as a signed byte.

· If both bounds are within the range 0..255 (Byte), the variable is stored as an unsigned byte.

· If both bounds are within the range -32768..32767 (Smallint), the variable is stored as a signed word.

· If both bounds are within the range 0..65535 (Word), the variable is stored as an unsigned word.

· If both bounds are within the range -2147483648..2147483647 (Longint), the variable is stored as a signed double word.

· If both bounds are within the range 0..4294967295 (Longword), the variable is stored as an unsigned double word.

· Otherwise, the variable is stored as a signed quadruple word (Int64).

整数类型变量的格式取决于它的最大范围和最小范围：

· 如果两个范围都是 -128..127（Shortint），那么变量存储为一个单字节（8位，即1字节）。

· 如果两个范围都是 0..255（Byte），那么变量存储为无符号的单字节（8位，即1字节）。

· 如果两个范围都是 -32768..32767（Smallint），那么变量存储为一个单字（16位，即2字节）。

· 如果两个范围都是 0..65535（Word），那么变量存储位一个无符号的单字（16位，即2字节）。

· 如果两个范围都是 -2147483648..2147483647（Longint），那么变量存储为一个含符号的双字（32位，即4字节）。

· 如果两个范围都是 0..4294967295（Longword），那么变量存储为一个无符号的双字（32位，即4字节）。

· 否则，变量存储为含符号的四个字（Int64）（64位，即8字节）。
