![]() 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. 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. 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. Thus, there is *NO* equals key ("=") as it is never needed (for more see ). RpnCalc is the best RPN calculator on the Android Market. 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 '='). You have the choice of using the keyboard or the UI buttons for input (touch screen capable where supported). 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). ![]() My use thus far has been cursory, but I look forward to exploring the features.A simple RPN calculator application opens in a popup window. I recently purchased the HP-15C clone called the DM15L. They knew a good product when they saw it and have saved the day by manufacturing a clone that seems nearly indistinguishable from the corresponding HP unit. These folks have taken the RPN baton and are running with it. It turns out that there is a manufacturer of Hewlett-Packard RPN clones called SwissMicros. Math Expression Renderer, Plots, Unit Converter, Equation Solver, Complex Numbers, Calculation History. ![]() Solve advanced problems in Physics, Mathematics and Engineering. My 12C now sits in the desk drawer with unused pens and paper clips. Scientific calculator with the RPN mode Graphic calculator options with eight equations already present Financial calculator which includes 10 worksheets. Robust and economical scientific calculator. Free Online Scientific Notation Calculator. Multi-replay lets you backtrack and edit expressions. Has 280 functions, including fractions, stats, and other calculations. The HP-12C financial calculator is a wholly inadequate substitute for a scientific calculator. Solid scientific calculator offers plentiful functions at a reasonable price. Only a few models remain on the market and several are financial calculators. here’s my shortlist of the 7 best scientific calculators: Casio FX-115ES PLUS. The application is designed for small screens (less than 5.8' smartphones or tablets with less than 2000 pixels on their largest side). It is quite intuitive to many of us and was a pleasure to use.īut, alas! The HP RPN calculator has largely gone out of fashion it seems. My RPN calculator is a scientific and financial calculator inspired by the Hewlett-Packard HP-10C series pocket calculators of the 80s, most notably the HP 12C and HP 15C models. The beauty of the RPN system with its 4 register stack was that it could do fairly elaborate chain calculations without the need for parentheses or an equal key. Of course I refer to those made by Hewlett-Packard. Graphing capabilities include labeled graphs and the ability to graph in polar coordinates, graph parametric equations, and more. I have been an enthusiastic user of RPN calculators since high school, when Gerry Ford was president. RPN Scientific is a scientific Reverse Polish Notation (RPN) calculator based on the venerable Hewlett Packard 10C scientific calculator. Scientific Graphing Calculator offers you typical functions in the Scientific mode, like the usual exponentiation and arithmetic functions, summations, sig figs, and complex numbers.
