tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem (Operator)

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem — Test whether the types of the elements of a tuple are of type real.

Signature

tuple_is_real_elem( : : T : IsReal)

Herror tuple_is_real_elem(double T, Hlong* IsReal)

Herror T_tuple_is_real_elem(const Htuple T, Htuple* IsReal)

void TupleIsRealElem(const HTuple& T, HTuple* IsReal)

HTuple HTuple::TupleIsRealElem() const

static void HOperatorSet.TupleIsRealElem(HTuple t, out HTuple isReal)

HTuple HTuple.TupleIsRealElem()

def tuple_is_real_elem(t: HTupleType) -> Sequence[int]

def tuple_is_real_elem_s(t: HTupleType) -> int

Description

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem tests the elements of the input tuple TTTtt separately. For all elements of type real the value 1 (true) is returned in IsRealIsRealIsRealisRealis_real, else 0 (false) is returned.

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_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem, which can be used in an expression in the following syntax:

IsReal := is_real_elem(T)

Attention

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem returns 2 ( H_MSG_TRUE) if the internal data type of the elements of the tuple is real. In contrast to tuple_is_numbertuple_is_numberTupleIsNumberTupleIsNumbertuple_is_number it does not return whether the elements of a tuple could be represented as real values.

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)  tuple(-array) → HTupleHTupleTypeHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)

Input tuple.

IsRealIsRealIsRealisRealis_real (output_control)  number(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Are the elements of the input tuple of type real?

Example (HDevelop)

tuple_is_real_elem ([3.1416,'pi',3,3.0], IsReal)
* IsReal = [true, false, false, true]

Result

If the parameters are valid, the operator tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemtuple_is_real_elem returns the value 2 ( H_MSG_TRUE) .
