Integer Types

Integer types may contain both positive and negative integer values. Integer values may range from -2,147,483,648 to 2,147,483,647 and other ranges are also supported. Each integer variable requires two bytes of storage. The following is a list of additional predefined integer types.

Integer Types:
TypeRangeFormat
ShortInt128 .. 127signed 8-bit
Integer2,147,483,648 .. 2,147,483,647signed 32-bit
SmallInt-32,768 .. 32,767signed 16-bit
LongInt2,147,483,648 .. 2,147,483,647signed 32-bit
Byte0 .. 255unsigned 8-bit
Word0 .. 65,535unsigned 16-bit
DWORD0 .. 4,294,967,295unsigned 32-bit
LongWord0 .. 4,294,967,295unsigned 32-bit
Cardinal0 .. 4,294,967,295unsigned 32-bit
Int64-2^63 .. 2^63 -1signed 64-bit
 On the Intel 386+ CPU's, operations performed with 32-bit integers are faster than operations with 16-bit ones. This is due to the fact that registers on the 32-bit processors are 32 bits wide.
