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.
