Extended emulator of МК 61/54 vs microMathematics Plus
Side-by-side comparison of two open source alternatives
Extended emulator of МК 61/54
МК 61 was the best seller of all USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52). Calculators are emulated on microcode level so they behave exactly like the original devices, including all non-documented features and inaccurate calculations. For ease of use application features saving and loading emulation states. This app's emulation engine Java code is based on C++ source of Felix Lazarev's emu145 project. Emulation was highly optimized for speed and should run in real time on any phone. It's an extended version of the original emulator МК 61/54 by Stanislav Borutsky (https://play.google.com/store/apps/details?id=com.cax.pmk). This version allows to export/import programs from external files and contains some UI improvements. Hint 0: you can found the list of all tips in the About dialog Hint 1: touch calculator's indicator to toggle slow/fast mode. Indicator's blinking looks better in slow mode. Hint 2: you can choose between MK-61 and MK-54 using menu option that becomes visible when calculator is switched off. Hint 3: with the menu "Import" you can import programs from external files, several such programs you can find in https://xvadim.github.io/xbasoft/pmk/pmk.html Hit 4: you can open menu by long tap on the "Вкл" label.
microMathematics Plus
With microMathematics Plus, you can not only perform mathematical calculations in naturally readable form, but can also create and manage your own collection of interactive formulas! The microMathematics Plus is a revolutionary new kind of mobile calculator. It is the world’s first scientific graphing calculator and function plotter on Android oriented around a worksheet. It allows live editing of mathematical identities combined with highly accurate computations. The app is 100% open source. Please feel free to download, explore, fork or contribute to it on https://github.com/mkulesh/microMathematics Not only students, but also everybody who likes mathematics or needs more than just a basic calculator will benefit from this amazing technique of mathematical calculations and plotting. Benefits and features: * Maximum privacy: No ads, no trackers, no telemetry, no special permissions * The modern Material design supports different color themes and works on smartphones and/or tablets in portrait and landscape mode * Verification, validation, documentation and re-use of mathematical calculations * Works on smartphone or tablet in portrait and landscape mode * Supports all commonly used mathematical operations * Mathematical expressions are written in an intuitive and naturally readable form * Supports SI and non-SI units (including units of information) * Powerful mathematical touch-screen editor with undo function makes editing easier * You can do multiple calculations and subsequently correct or change all used formulas * It is possible to store intermediate results into 1D, 2D, or 3D array that can improve calculation performance * Mathematical expressions are collected in a document, that includes not only formulas and plots, but also additional text and images (SVG format is also supported) * You can store your document on SD card and export it into LaTeX format or an image (SD writing permission is needed) * SD card on Android 6+ is also supported * The app contains detailed "How to use" page and several examples * Supports data import from ASCII files * Supports units of measurements, arrays, complex numbers, functions of many arguments, plots for several functions, contour and 3D plots, summation and product operations, derivative and definite integrals, if-function and logical operators, Fourier transform, root finding. This version has following mathematical limitations: it does not support special functions, vectors, matrices and many other things from high-level mathematics.
