(1) Arithmetic operation with BIN (Binary)
• If the operation result of an addition instruction exceeds 32767 , the result
becomes a negative value.
• If the operation result of a subtraction instruction is less than - 32768 , the result
becomes a positive value.
• The operation of a positive value and a negative value is as follows:
5 + 8 → 13
5 - 8 -3
→
5 x 3 15
→
-5 x 3 → -15
-5 x (-3) → 15
-5 / 3 -1 and remainder -2
→
5 / (-3) → -1 and remainder 2
-5 / (-3) → 1 and remainder -2
