tuple_is_inttuple_is_intTupleIsIntTupleIsInttuple_is_int (Operator)
Name
tuple_is_inttuple_is_intTupleIsIntTupleIsInttuple_is_int — Test if the internal representation of a tuple is of type integer.
Signature
Herror tuple_is_int(const Hlong T, Hlong* IsInt)
Herror T_tuple_is_int(const Htuple T, Htuple* IsInt)
def tuple_is_int(t: HTupleType) -> int
Description
tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int tests if the internal representation of the
input tuple TTTTtt is of type integer. In that case
the value 1 (true) is returned in IsIntIsIntIsIntIsIntisIntis_int, otherwise the value
0 (false) is returned. If a tuple consists of integer elements only,
IsIntIsIntIsIntIsIntisIntis_int can nevertheless be 0 in case the internal representation
is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypeTupleTypeTupleTypetuple_type 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_intTupleIsIntTupleIsIntTupleIsInttuple_is_int,
which can be used in an expression in the following syntax:
IsInt := is_int(T)
Attention
Even if all tuple elements are of type integer,
tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int 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_elemTupleIsIntElemTupleIsIntElemTupleIsIntElemtuple_is_int_elem
should be used.
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
TTTTtt (input_control) tuple(-array) → HTupleHTupleTypeHTupleHtuple (integer / real / string / handle) (int / long / double / string / HHandle) (Hlong / double / HString / HHandle) (Hlong / double / char* / handle)
Input tuple.
IsIntIsIntIsIntIsIntisIntis_int (output_control) number → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Is the input tuple of type integer?
Example (HDevelop)
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
Result
If the parameters are valid, the operator
tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int returns the value TRUE.
