-The `ABS` function can produce an overflow error when the absolute value of a number is greater than the largest number that can be represented by the specified data type. For example, the `int` data type can hold only values that range from `-2,147,483,648` to `2,147,483,647`. Computing the absolute value for the signed integer `-2,147,483,648` causes an overflow error because its absolute value is greater than the positive range for the `int` data type.
