tuple_negtuple_negTupleNegTupleNegtuple_neg (Operator)

tuple_negtuple_negTupleNegTupleNegtuple_neg — Negate a tuple.

Signature

tuple_neg( : : T : Neg)

Herror tuple_neg(double T, double* Neg)

Herror T_tuple_neg(const Htuple T, Htuple* Neg)

void TupleNeg(const HTuple& T, HTuple* Neg)

HTuple HTuple::TupleNeg() const

static void HOperatorSet.TupleNeg(HTuple t, out HTuple neg)

HTuple HTuple.TupleNeg()

def tuple_neg(t: MaybeSequence[Union[float, int]]) -> Sequence[Union[float, int]]

def tuple_neg_s(t: MaybeSequence[Union[float, int]]) -> Union[float, int]

Description

tuple_negtuple_negTupleNegTupleNegtuple_neg computes the negation of the input tuple TTTtt, i.e., NegNegNegnegneg = -TTTtt. The negation of an integer number is again an integer number. The negation of a floating point number is a floating point number. The negation of a string is not allowed.

Exception: Empty input tuple

If the input tuple is empty, the operator returns an empty tuple.

HDevelop In-line Operation

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

Neg := -T

Execution Information

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

Parameters

TTTtt (input_control)  number(-array) → HTupleMaybeSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)

Input tuple.

NegNegNegnegneg (output_control)  number(-array) → HTupleSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)

Negation of the input tuple.
