Operation Principle

This is a basic arithmetic function with real and integer data types. The setting AritmetType selects
the arithmetic operation to be performed on the two inputs.
AritmetType = "Addition"
• REALOUT = REALIN1 + REALIN2
• INTOUT = INTIN1 + INTIN2
AritmetType = "Subtraction"
• REALOUT = REALIN1 – REALIN2
• INTOUT = INTIN1 – INTIN2
AritmetType = "Multiplication"
