Optional documentation of this object. If this object is an operator, the Documentation text is displayed below the operator symbol.


A calculation of 10Log of the value 0 or negative values is not allowed. If the 10Log calculation cannot be performed, the operator outputs the last valid sample once more. The symbol of the 10Log will then display a warning.


Example: Log - Ln - Exp Demo
This 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.
