(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 : Stored at the lower 32 bits.
Remainder : Stored at the upper 32 bits (Stored only when using a word device).
(3) The values for and

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.

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.
