## Calculator

If you select Calculator from the Tools menu or if you simply click on the calculator icon at the buttonbar you can launch the calculator. By default, the standard calculator will be used that is offered by your operating system.
If for some reason the standard calculator cannot be found or if you prefer to use a different calculator program for the NC you can specify your preferred calculator program by setting the JVM option called calculator:
-Dcalcualtor=<my calculator>
Example for GNU/Linux:
java -Dcalculator=/usr/bin/speedcrunch -jar nc.jar
