(2) With a word device, the division operation result is stored in 64 bits and both the quotient
and remainder are stored. With a bit device, only the quotient is stored as the operation
result in 32 bits.
Quotient
Remainder :
(3) The values for

(4) Judgment whether values for
basis of the most significant bit (b31).
(Sign is attached to both the quotient and remainder.)
• 0: Positive
• 1: Negative
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) is turned ON,
and the corresponding error code is stored into SD0.
• Attempt to divide
Program Example
(1) The following program multiplies the BIN data at D7 and D8 by the BIN data at D18 and D19
when X5 is ON, and stores the result at D1 to D4.
[Ladder Mode]
(2) The following program outputs the value resulting when the data at X8 to XF is multiplied by
3.14 to Y30 to Y3F when X3 is ON.
