The INTEGER data type can accept numbers with absolute values from 0 to 2,147,483,647 (plus or minus (2 to the 31st power) - 1). If you have to store numbers outside this range, redefine the column or variable to use DECIMAL data type. (The value -2,147,483,648 is a 32-bit value but is not acceptable; it is used in 4GL to indicate a null value.)
