tuple_rsh — Shift a tuple bitwise to the right.
tuple_rsh shifts the tuple T bitwise to the right
by Shift places. This operation is equivalent to a
division by 2^{Shift}. If T is negative, the
result depends on the hardware. If Shift is negative or
larger than 32, the result is undefined. If both tuples have the
same length the corresponding elements of both tuples are shifted.
Otherwise, either T or Shift must have length 1.
In this case, the operation is performed for each element of the
longer tuple with the single element of the other tuple. The input
tuples must contain only integer numbers.
If any of the input tuples is empty, the operator returns an empty tuple.
HDevelop provides an in-line operation for tuple_rsh,
which can be used in an expression in the following syntax:
T (input_control) integer(-array) → (integer)
Input tuple.
Shift (input_control) integer(-array) → (integer)
Number of places to shift the input tuple.
Rsh (output_control) integer(-array) → (integer)
Shifted input tuple.
