Boolean Operand Description
+ S, D (D) + (S) → (D)
D+ S, D (D +1, D) + (S+1, S) → (D+1, D)
+ S1, S2, D (S1) + (S2) → (D)
D+ S1, S2, D (S1+1, S1) + (S2+1, S2) → (D+1, D)
- S, D (D) - (S) → (D)
S, D (D+1, D) - (S+1, S) → (D+1, D)
D-
- S1, S2, D (S1) - (S2) → (D)
D- S1, S2, D (S1+1, S1) - (S2+1, S2) → (D+1, D)
* S1, S2, D (S1) × (S2) → (D+1, D)
D* S1, S2, D (S1+1, S1) × (S2+1, S2) → (D+3, D+2, D+1, D)
% S1, S2, D (S1) ÷ (S2) → quotient (D) remainder (DT90015)
D% S1, S2, D (S1+1, S1) ÷ (S2+1, S2) → quotient (D+1, D)
remainder (DT90016, DT90015)
*W S1, S2, D (S1) × (S2) → (D)
+1 D (D) + 1 → (D)
D+1 D (D+1, D) + 1 → (D+1, D)
- 1 D (D) - 1 → (D)
D- 1 D (D+1, D) - 1 → (D+1, D)
D*D S1, S2, D (S1+1, S1) × (S2+1, S2) → (D+1, D)
