Open Source Calculators

Easy, quick and useful calculator. Lighter enough for quick calculations and powerful enough to provide the most complicated computations.

AlphaCentauri is a completely free office application, with various utilities resembling those distributed commercially on Windows. Functionalities are still quite limited compared to the commercial products, but more features will be added soon. Please note that update v1.1.0 has full featured programs, however you will see a watermark with "trial version" details. This is due to some features were used through Nevron's very useful and awesome libraries. Unfortunately, these libraries and dev tools are also very expensive. This should not interfere with working comfortably and saving clean docs. This is just a release version until I get my head around building those trialed features from scratch. If watermarks turn out annoying, one can always download the v.1.0.3 with basic features and UI.

Fast calculator is fast and simple calculator with many functions on java.

Generates the Reverse Polish Notation (Postfix) expression form of an arithmetic expression in (Infix) form. Performs the computation of the arithmetic expression if Integers or Floating point numbers are used in the expression. Supports PEDMAS order of computation, thus, all the operators of Exponentiation, Division, Multiplication, Addition and Subtraction, as well as using Parentheses for grouping and prioritization is all handled.

MiniCalc GUI is a calculator that supports user-defined functions and graphing. It starts instantly and runs on both Windows and Linux. It is easy to use for the average user, but also supports factorials, exponents, logs, and trig functions.

-> miniColors is replaced by Colora (https://colora.sourceforge.io). <- miniWork is a project which includes a group of small and simple VB.Net WinForms office applications. It consists of the text and rich text editor miniEditor, the simple calculator miniCalc, the color picker miniColors and the image viewing program miniViewer. All applications are independent programs which are put together in this project. The project is kept very simple, so all applications only provide the most basic functions.
