Arithmetic operations

FUN	Name			Expression				Function	Steps	Speed	Page
No.										(∝ s)
027	Addition	− [ A +		B →		C ]−		Adds data of A and B, and	4	6.5	143
								stores the result in C.
028	Subtraction	− [ A -	B →			C ]−		Subtracts data of B from A,	4	6.5	144
								and stores the result in C.
029	Multiplication	− [ A ∗		B →		C+1⋅C ]−		Multiplies data of A and B,
								and stores the result in	4	8.8	145
								double-length register C+1⋅C.
030	Division	− [ A /	B →			C ]−		Divides data of A by B, and
								stores the quotient in C and	4	9.7	146
								the reminder in C+1.
031	Double-word	− [ A+1⋅A D+			B+1⋅B →		C+1⋅C ]−	Adds data of A+1⋅A and
	addition							⋅	4	11.6	147
								B+1 B, and stores the result
								in C+1⋅C.
032	Double-word	− [ A+1⋅A D-			B+1⋅B →		C+1⋅C ]−	Subtracts data of B+1 B from
								⋅
	subtraction							⋅	4	11.7	148
								A+1 A, and stores the result
								in C+1⋅C.
035	Addition with	− [ A +C B →				C ]−		Adds data of A, B and the
	carry							carry, and stores the result in	4	9.7	149
								C. The carry flag changes
								according to the result.
036	Subtraction	− [ A -C		B →		C ]−		Subtracts data of B and the
	with carry							carry from A, and stores the	4	9.7	150
								result in C. The carry flag
								changes according to the
								result.
039	Unsigned	− [ A U∗		B →		C+1⋅C ]−		Multiplies data of A and B,
	multiplication							and stores the result in	4		151
								double-length register C+1⋅C.
								(Unsigned integer operation)
040	Unsigned	− [ A U/		B →		C ]−		Divides data of A by B, and
	division							stores the quotient in C and	4		152
								the reminder in C+1.
								(Unsigned integer operation)
041	Unsigned	− [ A+1⋅A DIV B →					C ]−	Divides data of A+1 A by B,
								⋅
	double/single							and stores the quotient in C	4	15.3	153
	division							and the reminder in C+1.
								(Unsigned integer operation)
043	Increment	− [ +1	A ]−					Increments data of A by 1.	2	4.6	154
044	Decrement	− [ -1 A ]−						Decrements data of A by 1.	2	4.6	155
