PACSystems* RX7i, RX3i and RSTi-EP CPU Programmer's Reference Manual
Multiplies two through eight operands (IN1 ... IN8) of the
same data type and stores the result in the output variable
assigned to Q, also of the same data type.
The output is calculated when the function is performed
without Overflow, unless an invalid operation occurs.
If an Overflow occurs, the result wraps around.
Displays as
base 10 number with sign, up to 5 digits long
base 10 number with sign, up to 10 digits long
base 10 number, sign and decimals, up to 8 digits long
(excluding the decimals)
base 10 number, unsigned, up to 5 digits long
