Documentationtype: See description
Optional documentation of this object. If this object is an operator, the Documentation text is displayed below the operator symbol.
DetailsIf the calculation cannot be performed (invalid input values), the operator outputs the last valid sample once more. The symbol in the designer will then display a warning.
Example: Log - Ln - Exp DemoThis demo shows the behavior of the 10Log, Ln and e^y operators. Press 'Start displays' first so that the numerical displays display values. Then type values in the Input Field.
Note the behavior of the operators when they are forced to do illegal calculations. They will show a warning about any problems, but keep their output unchanged.
