MulOU (*OU)
MulOU (*OU)
The MulOU (*OU) instruction multiplies integers and real numbers and outputs the result. It also per-
forms an overflow/underflow check.
* If you omit the input parameter that connects to InN, the default value is not applied, and a building error will occur. For
example, if N is 3 and the input parameters that connect to In1 and In2 are omitted, the default values are applied, but if the
input parameter that connects to In3 is omitted, a building error will occur.
The MulOU (*OU) instruction multiplies between two and five integers and real numbers and outputs
the result. The data types of values to multiply In1 to InN and multiplication result Out can have different
data types. If the multiplication result exceeds the valid range of the data type that includes all of the
data types of In1 to InN, the value of the P_CY system-defined variable (Carry Flag) changes to TRUE.
This indicates that an overflow or an underflow has occurred.
If Out is a real number and an overflow or underflow occurs, the value of Out is positive or negative
infinity. If Out is an integer, only the bits of the multiplication result that fit in the data type of Out are
assigned to Out.
