Longint - an integer whose size is guaranteed to be 32 bits
<![CDATA[
type LongInt = -2147483648..2147483647;
Description
The LongInt type is a 32 bit signed Integer. This size is fixed, and will not change in future releases of Delphi. It is currently the same size as the Integer type.
To hold very large signed integers, use the Int64 type.

Example code : Showing the capacity of LongInt
var
min, max : LongInt;
begin
// Set the minimum and maximum values of this data type
min := Low(LongInt);
max := High(LongInt);
ShowMessage('Min longint value = '+IntToStr(min));
ShowMessage('Max longint value = '+IntToStr(max));
end;
