tuple_is_int🔗
Short description🔗
tuple_is_int — Test if the internal representation of a tuple is of type integer.
Signature🔗
tuple_is_int( tuple T, out number IsInt )
Description🔗
tuple_is_int tests if the internal representation of the
input tuple T is of type integer. In that case
the value 1 (true) is returned in IsInt, otherwise the value
0 (false) is returned. If a tuple consists of integer elements only,
IsInt can nevertheless be 0 in case the internal representation
is H_TYPE_MIXED; see tuple_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_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_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_elem
should be used.
Execution information🔗
Execution information
-
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
-
Multithreading scope: global (may be called from any thread).
-
Processed without parallelization.
Parameters🔗
T (input_control) tuple(-array) → (integer / real / string / handle)
Input tuple.
IsInt (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_int returns the value 2 (H_MSG_TRUE).
