The maximum value of Signed Short is = 32767
The maximum value of Unsigned Short is = 65535
The minimum value of Signed INT is = -2147483648
The maximum value of Signed INT is = 2147483647
The maximum value of Unsigned INT is = 4294967295
The minimum value of Signed LONG is = -9223372036854775808
The maximum value of Signed LONG is = 9223372036854775807
The maximum value of Unsigned LONG is = 18446744073709551615
