EBTCalc is an open-source, programmable Reverse Polish Notation (RPN) calculator developed by Eric Bergman-Terrell for Android and desktop platforms. It stands out from standard calculators by allowing users to completely customize its interface using JavaScript. Key Features
Programmable Custom Buttons: You can write custom functions in JavaScript using a built-in script editor. This lets you automate complex formulas and execute them with a single custom button tap.
True RPN Mechanics: Operations are performed directly on an entry stack without the need for parentheses.
Infinite Stack & Persistent Memory: EBTCalc features an unlimited stack depth. The values on your stack and your named memory variables remain safely stored even after you close and restart the application.
Array Processing: It manipulates entire data arrays with floating-point ease. You can convert stack values to and from arrays with a single click.
Computer Math: EBTCalc includes advanced functions for bitwise logical operations, binary/hex arithmetic, and base conversions. Cross-Platform Availability:
Desktop: Built using the Electron framework, it runs natively on 64-bit Windows and Linux (Intel/AMD and ARM). The code and binaries are hosted publicly on the EricTerrell/EBTCalc GitHub Repository.
Android: Optimized for all form factors. It features an efficient two-column mode for large tablets. Core Mathematics Capabilities
Beyond custom script automation, EBTCalc includes an extensive catalog of built-in features:
Full trigonometry, algebra, and advanced statistical analysis. Computer engineering math functions. Date and time duration manipulations.
Complete clipboard integration to copy/paste values to and from external apps. A clean, ad-free UI that respects screen real-estate.
