tuple_is_int_elemtuple_is_int_elemTupleIsIntElemTupleIsIntElem (Operator)

Name

tuple_is_int_elemtuple_is_int_elemTupleIsIntElemTupleIsIntElem — Test whether the types of the elements of a tuple are of type integer.

Signature

tuple_is_int_elem( : : T : IsInt)

Herror tuple_is_int_elem(const Hlong T, Hlong* IsInt)

Herror T_tuple_is_int_elem(const Htuple T, Htuple* IsInt)

void TupleIsIntElem(const HTuple& T, HTuple* IsInt)

HTuple HTuple::TupleIsIntElem() const

static void HOperatorSet.TupleIsIntElem(HTuple t, out HTuple isInt)

HTuple HTuple.TupleIsIntElem()

Description

tuple_is_int_elemtuple_is_int_elemTupleIsIntElemTupleIsIntElemTupleIsIntElem tests the elements of the input tuple TTTTt separately. For all elements of type integer the value 1 (true) is returned in IsIntIsIntIsIntIsIntisInt, 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_int_elemtuple_is_int_elemTupleIsIntElemTupleIsIntElemTupleIsIntElem, which can be used in an expression in the following syntax:

IsInt := is_int_elem(T)

Attention

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

Execution Information

Parameters

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

Input tuple.

IsIntIsIntIsIntIsIntisInt (output_control)  number(-array) HTupleHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Are the elements of the input tuple of type integer?

Example (HDevelop)

tuple_is_int_elem ([3.1416,'pi',3,3.0], IsInt)
* IsInt = [false, false, true, false]

Result

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