        public long evaluateBinary​(int sizeout,
                                   int sizein,
                                   long in1,
                                   long in2)
        Description copied from class: BinaryOpBehavior
        Evaluate the binary (2 input args) operation using long data
        Specified by:
        evaluateBinary in class BinaryOpBehavior
        Parameters:
        sizeout - intended output size (bytes)
        sizein - in1 size (bytes)
        in1 - unsigned input 1
        in2 - unsigned input 2
        Returns:
        operation result. NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed long value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.
