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)
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
- 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 (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).
