Simple_Integer

The SIMPLE_INTEGER data type is a subtype of BINARY_INTEGER. The SIMPLE_INTEGER can store the same range as BINARY_INTEGER. The SIMPLE_INTEGER cannot store a NULL value. The range of values SIMPLE_INTEGER can store is -2³¹ (-2,147,483,648) to 2³¹ (2,147,483,648).

Arithmetic overflow is truncated when using SIMPLE_INTEGER values.
