A value of 1 is added to the integer or double-length integer data. No overflow or underflow will occur for either an
integer or double-length integer. This operation handles overflows and underflows in the same way as the ADDX
instruction.

Output Data Behavior
ΠIn the example shown above, the data is an integer. With double-length integers, adding 1 to 2,147,483,647
(7FFFFFFF hex) results in -2,147,483,648(80000000 hex).
