      • evaluateUnary

        public long evaluateUnary​(int sizeout,
                          int sizein,
                          long in1)
        Description copied from class: UnaryOpBehavior
        Evaluate the unary operation using long data
        Specified by:
        evaluateUnary in class UnaryOpBehavior
        Parameters:
        sizeout - intended output size (bytes)
        sizein - in1 size (bytes)
        in1 - unsigned input 1
        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.
