tuple_is_inttuple_is_intTupleIsIntTupleIsInt (Operator)

Name

tuple_is_inttuple_is_intTupleIsIntTupleIsInt — Test if the internal representation of a tuple is of type integer.

Signature

tuple_is_int( : : T : IsInt)

Description

tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInt tests if the internal representation of the input tuple TTTTt is of type integer. In that case the value 1 (true) is returned in IsIntIsIntIsIntIsIntisInt, otherwise the value 0 (false) is returned. If a tuple consists of integer elements only, IsIntIsIntIsIntIsIntisInt can nevertheless be 0 in case the internal representation is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypeTupleTypeTupleType 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_intTupleIsIntTupleIsIntTupleIsInt, 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_intTupleIsIntTupleIsIntTupleIsInt 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_elemTupleIsIntElemTupleIsIntElemTupleIsIntElem 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

TTTTt (input_control) tuple(-array) → (integer / real / string / handle)

Input tuple.

IsIntIsIntIsIntIsIntisInt (output_control) number → (integer)

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_intTupleIsIntTupleIsIntTupleIsInt returns the value 2 (H_MSG_TRUE).
