2.4.1 Double-word multiplication and division (D )
FUN 042
D /
Expression
Input ─[ A+1 A D / B+1 B
Function
When the input is ON, the data of A+1 A is multiplied by the data of B+1 B, and the product is divided by
B+3 B+2, then the quotient is stored in C+1 C and the remainder in C+3 C+2.
The data range is -2147483648 to 2147483647. If the result (quotient) is out of the data range, the following
limit value is stored.
Positive overflow: quotient = 2147483647, remainder = 0
Negative overflow: quotient = -2147483647, remainder = 0

Example
When R0200 is ON, the double-word data of D0351 D0350 is multiplied by the data of D0262 D0261,
and the product is divided by the data of D0264 D0263, then the quotient is stored in D0401 D0400 and
the remainder in D0403 D0402.
