tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElem (Operator)

Name

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElem — 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()

Description

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElem tests the elements of the input tuple TTTTt separately. For all elements of type real the value 1 (true) is returned in IsRealIsRealIsRealIsRealisReal, 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_elemTupleIsRealElemTupleIsRealElemTupleIsRealElem, which can be used in an expression in the following syntax:

IsReal := is_real_elem(T)

Attention

tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElem returns true if the internal data type of the elements of the tuple is real. In contrast to tuple_is_numbertuple_is_numberTupleIsNumberTupleIsNumberTupleIsNumber it does not return whether the elements of a tuple could be represented as real values.

Execution Information

Parameters

TTTTt (input_control)  tuple(-array) HTupleHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)

Input tuple.

IsRealIsRealIsRealIsRealisReal (output_control)  number(-array) HTupleHTupleHtuple (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_elemTupleIsRealElemTupleIsRealElemTupleIsRealElem returns the value 2 (H_MSG_TRUE).
