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.

Examples

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.
