tuple_lshtuple_lshTupleLshtuple_lshTupleLshTupleLsh (Operator)

Name

tuple_lshtuple_lshTupleLshtuple_lshTupleLshTupleLsh — Shift a tuple bitwise to the left.

Signature

Description

tuple_lshtuple_lshTupleLshtuple_lshTupleLshTupleLsh shifts the tuple TTTTTt bitwise to the left by ShiftShiftShiftShiftShiftshift places. If no overflow occurs, this operation is equivalent to a multiplication by 2^{ShiftShiftShiftShiftShiftshift}. If TTTTTt is negative, the result depends on the hardware. If ShiftShiftShiftShiftShiftshift 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 TTTTTt or ShiftShiftShiftShiftShiftshift 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.

Exception: Empty input tuples

If either or both of the input tuples are empty, the operator returns an empty tuple.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_lshtuple_lshTupleLshtuple_lshTupleLshTupleLsh, which can be used in an expression in the following syntax:

Lsh := lsh(T, Shift)

Parallelization

• Multithreading type: independent (runs in parallel even with exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
