tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt — Test whether a tuple is of type integer.
Herror tuple_is_int(const Hlong T, Hlong* IsInt)
Herror T_tuple_is_int(const Htuple T, Htuple* IsInt)
Herror tuple_is_int(const HTuple& T, Hlong* IsInt)
tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt tests the input tuple TTTTTt.
If the type is integer, the value 1 (true) is returned in
IsIntIsIntIsIntIsIntIsIntisInt, else 0 (false) is returned. If a tuple consists of
integer elements only, IsIntIsIntIsIntIsIntIsIntisInt can nevertheless be 0
in case the internal representation is H_TYPE_MIXED; see
tuple_typetuple_typeTupleTypetuple_typeTupleTypeTupleType for details.
tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt returns true if the internal data type of the
tuple is integer. In contrast to tuple_is_numbertuple_is_numberTupleIsNumbertuple_is_numberTupleIsNumberTupleIsNumber
it does not return whether a tuple could be represented as or converted
to a tuple of integer values.
- 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 integer?
tuple_is_int ([3.1416,'pi',3], IsIntA)
* IsIntA = false
tuple_is_int ([1,2,3], IsIntB)
* IsIntB = true
tuple_is_int ([], IsIntC)
* IsIntC = true
If the parameters are valid, the operator
tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt returns the value 2 (H_MSG_TRUE).
