3.26.3 Arithmetic Operation Instructions

The arithmetic operation instructions are instructions which perform the addition, subtraction, multiplication, and division of two BIN data.

(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
