tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal — Test if the internal representation of a tuple is of type real.
Herror tuple_is_real(double T, Hlong* IsReal)
Herror T_tuple_is_real(const Htuple T, Htuple* IsReal)
Herror tuple_is_real(const HTuple& T, Hlong* IsReal)
tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal tests if the internal representation of the
input tuple TTTTTt is of type real. In that case
the value 1 (true) is returned in IsRealIsRealIsRealIsRealIsRealisReal, otherwise the value
0 (false) is returned. If a tuple consists of real elements only,
IsRealIsRealIsRealIsRealIsRealisReal can nevertheless be 0 in case the internal representation
is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypetuple_typeTupleTypeTupleType for details.
Even if all tuple elements are of type real,
tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal returns 0 (false) if the internal representation
of the tuple is of type H_TYPE_MIXED. To test if the elements of the
tuple are of type real the operator tuple_is_real_elemtuple_is_real_elemTupleIsRealElemtuple_is_real_elemTupleIsRealElemTupleIsRealElem
should be used.
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Input tuple.
Is the input tuple of type real?
tuple_is_real ([3.1416,'pi',3], IsRealA)
* IsRealA = false
tuple_is_real ([1.0,2.0,3.0], IsRealB)
* IsRealB = true
tuple_is_real ([], IsRealC)
* IsRealC = true
If the parameters are valid, the operator
tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal returns the value 2 (H_MSG_TRUE).
