### Cardinal

#### Synopsis

         type
           Cardinal  { built-in type }

#### Description

`Cardinal` is the “natural” unsigned integer type in GNU Pascal. On some platforms it is 32 bits wide and thus has a range of `0 .. 4294967295`. Use it whenever you need a general-purpose unsigned integer type and don't need to care about compatibility to other Pascal dialects.

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

#### Conforming to

`Cardinal` is not defined in ISO Pascal, but several Pascal compilers support it as an extension. In Borland Delphi, for instance, it is an unsigned 16-bit in version 1.0, an unsigned 31-bit integer from version 2.0 on, and an unsigned 32-bit integer from version 4.0 on.

#### Example

         program CardinalDemo;
         var
           a: Cardinal;
         begin
           a := 42;
           WriteLn (a)
         end.
