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)
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
- 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) → HTupleHTupleHtuple (integer / real / string / handle) (int / long / double / string / HHandle) (Hlong / double / HString / HHandle) (Hlong / double / char* / handle)
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).
