type Integer = -2147483648..2147483647; // At the time of writing Description The Integer type is an Integer whose size is not guaranteed. It is the basic integer type in Delphi, and currently has the same capacity as the LongInt type - 1 bit sign, and 31 bits value. To hold very large integers, use the Int64 type. Related commands Byte An integer type supporting values 0 to 255 Cardinal The basic unsigned integer type Int64 A 64 bit sized integer - the largest in Delphi LongInt An Integer whose size is guaranteed to be 32 bits LongWord A 32 bit unsigned integer ShortInt An integer type supporting values -128 to 127 SmallInt An Integer type supporting values from -32768 to 32767 Word An integer type supporting values 0 to 65535 Example code : Showing the capacity of Integer var min, max : Integer; begin // Set the minimum and maximum values of this data type min := Low(Integer); max := High(Integer); ShowMessage('Min integer value = '+IntToStr(min)); ShowMessage('Max integer value = '+IntToStr(max)); end; Show full unit code Min integer value = -2147483648 Max integer value = 2147483647
