8 Function Instructions
8.2 Arithmetic Operation Instructions
D/
 Divides BIN bit data designated by (S1) and BIN bit data designated by (S2), and stores the division result in the device
designated by (D).
S1+1 S1
b31 b16 b15 b0
567890 (BIN) /
 If a word device has been used, the result of the division operation is stored as 64 bits, and both the quotient and remainder
are stored.
Quotient: Stored at the lower 32 bits
Remainder: Stored at the upper 32 bits
 The values for (S1) and (S2) can be designated between -2147483648 and 2147483647 (BIN 32 bits).
 Judgment whether values for (S1), (S2), (D), and (D)+2 are positive or negative is made on the basis of the most significant
bit (b31).
(A sign is used with both the quotient and the remainder)
b31 Judgment (+/-)
0 Positive
1 Negative
 When divisor S2 is "0", no operation is carried out.
 Operation errors
 There are no arithmetic errors associated with the "D*", "D*P, "D/", or "D/P" instructions.
 Program example
 When X5 is turned ON, multiplication result of BIN data of D7 and D8 and BIN data of D18 and D19 is stored in D1 to D4.

 When X3 is turned ON, the data of X8 to XF is multiplied by 3.14 and the result is output to Y30 to Y3F.
