tuple_is_real_elem🔗
Short description🔗
tuple_is_real_elem — Test whether the types of the elements of a tuple are of type real.
Signature🔗
tuple_is_real_elem( tuple T, out number IsReal )
Description🔗
tuple_is_real_elem tests the elements of the input tuple T
separately.
For all elements of type real the value 1 (true) is returned in
IsReal, else 0 (false) is returned.
Exception: Empty input tuple🔗
If the input tuple is empty, the operator returns an empty tuple.
HDevelop In-line Operation🔗
HDevelop provides an in-line operation for tuple_is_real_elem,
which can be used in an expression in the following syntax:
IsReal := is_real_elem(T)
Attention🔗
tuple_is_real_elem returns 2 (H_MSG_TRUE) if the internal data type
of the elements of the tuple is real. In contrast to
tuple_is_number it does not return whether the elements of a tuple
could be represented as real values.
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) → (real / integer / string / handle)
Input tuple.
IsReal (output_control) number(-array) → (integer)
Are the elements of the input tuple of type real?
Example🔗
(HDevelop)
tuple_is_real_elem ([3.1416,'pi',3,3.0], IsReal)
* IsReal = [true, false, false, true]
Result🔗
If the parameters are valid, the operator
tuple_is_real_elem returns the value 2 (H_MSG_TRUE).
