9.125 Integer

Synopsis

 
type
  Integer  { built-in type }
or
 
type
  Integer (n)  { built-in type class }

Description

`Integer' is the "natural" signed integer type in GNU Pascal. On most platforms it is 32 bits wide and thus has a range of `-2147483648 .. 2147483647'. Use it whenever you need a general-purpose signed integer type.

As an extension, GPC allows to use `Integer' as a pseudo-schema to produce types with a specified size in bits; for example

 
type
  Int16 = Integer (16);

defines an integer type with 16 bits. The same mechanism works for `Cardinal' and `Word', too.

`Integer' in GNU Pascal is compatible to `Int' in GNU C.

There are lots of other integer types in GPC, see section 8.2.3 Integer Types.

Conforming to

In ISO Pascal, `Integer' is the only built-in integer type. (However see section 8.2.10.1 Subrange Types.)

Example

 
program IntegerDemo;
var
  a: Integer;
begin
  a := 42;
  WriteLn (a)
end.
