Description
A simple RPN calculator application; opens in a popup window. RPN Calculator is a simple yet powerful calculator that uses Reverse Polish Notation as the basis of its operation (in RPN, every operator follows all of its operands). You have the choice of using the keyboard or the UI buttons for input (touch screen capable where supported). NOTE: For those looking for a regular calculator, this calculator works differently! To use an RPN calculator to add 2 and 3 together, you enter '2' then the 'ENTER' key then '3' and finally '+' to get your answer (whereas in a regular calculator you enter '2' then '+' then '3' then '='). Thus, there is *NO* equals key ("=") as it is never needed (for more see http://bit.ly/1gVaSq4). The screenshot image shows the basic and scientific operators currently available; these include plus, minus, multiply, divide, square root, square, y^x, sin, cosine, tangent, natural logarithm and pi. This app runs offline; i.e., the Chrome browser does not have to be running for the app to run, nor is a connection to the internet required. Note: Also available as a Chrome "packaged app" (seamlessly integrates into your ChromeBook or desktop environment and can also be invoked from the desktop menu and/or from a desktop icon (like a standalone app)) - the "packaged app" version will be available as soon as the Chrome Web Store allows.
