tuple_lshtuple_lshTupleLshTupleLshtuple_lsh (Operator)
Name
tuple_lshtuple_lshTupleLshTupleLshtuple_lsh — Shift a tuple bitwise to the left.
Signature
Herror tuple_lsh(const Hlong T, const Hlong Shift, Hlong* Lsh)
Herror T_tuple_lsh(const Htuple T, const Htuple Shift, Htuple* Lsh)
def tuple_lsh(t: MaybeSequence[int], shift: MaybeSequence[int]) -> Sequence[int]
def tuple_lsh_s(t: MaybeSequence[int], shift: MaybeSequence[int]) -> int
Description
tuple_lshtuple_lshTupleLshTupleLshtuple_lsh shifts the tuple TTTtt bitwise to the left by
ShiftShiftShiftshiftshift places. If no overflow occurs, this operation is
equivalent to a multiplication by 2^{ShiftShiftShiftshiftshift}. If TTTtt
is negative, the result depends on the hardware. If ShiftShiftShiftshiftshift
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 TTTtt or ShiftShiftShiftshiftshift
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_lshTupleLshTupleLshtuple_lsh,
which can be used in an expression in the following syntax:
Lsh := lsh(T, Shift)
Execution Information
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
