[Operation Errors]
(1) In the following cases an operation error occurs, the error flag (SM0) turns ON, and an error
code is stored at SD0.
• The contents of the designated device or the result of the multiplication or division operation
are not "0", or not within the following range: (Error code: 4100)

• When the specified device contains -0 (Q4ARCPU)
(Operation error does not occur even if -0 is stored if SM707 is turned on.) (Error code: 4100)
[Program Example]
(1) The following program multiplies the floating decimal point real numbers at D3 and D4 and the
floating decimal point real numbers at D10 and D11, and stores the result at R0 and R1.
[Ladder Mode]
(2) The following program divides the floating decimal point real numbers at D10 and D11 by the
floating decimal point real numbers at D20 and D21, and stores the result at D30 and D31.
