tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt — Test if the internal representation of 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 if the internal representation of the
input tuple TTTTTt is of type integer. In that case
the value 1 (true) is returned in IsIntIsIntIsIntIsIntIsIntisInt, otherwise the value
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.
Exception: Empty input tuple
If the input tuple is empty, the operator returns 1.
HDevelop In-line Operation
HDevelop provides an in-line operation for tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt,
which can be used in an expression in the following syntax:
IsInt := is_int(T)
Even if all tuple elements are of type integer,
tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt 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 integer the operator tuple_is_int_elemtuple_is_int_elemTupleIsIntElemtuple_is_int_elemTupleIsIntElemTupleIsIntElem
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 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).
