Computator.NET is a unique open numerical software that is fast and easy to use and stands up to other feature-wise software. Quick presentation of Computator.NET features

Its features include:

  • Real, complex and two-variable (3D) function charts
  • Real, complex and two-variable (3D) function calculator
  • Numerical calculations on real functions including many different methods
  • Over 107 Elementary functions
  • Over 141 Special functions
  • Over 21 Matrix functions and operations
  • Original scripting language designed for scientists, powerful for easy computations including matrices
  • User-created custom functions written with scripting language
  • Mathematical notation, including raising to power, just like it should be

Release 2.1 beta

This release is focused on making Computator.NET more stable. There are over 50 serious bugs and inconsistencies fixed since 2.0 release.

Installation & Setup

  1. This project requires .NET Framework at least in version 4.0 Full, you can download it here (
  2. Go to latest release page
  3. Now you can download either portable version (the one with .zip extension) or installer (the one with .exe extension). In general, installer is recommended, because it sets up tsl and tslf files extensions for Computator.NET in registry.
  4. If you downloaded portable version, just unzip it into location you want to store and you are ready to go.
  5. If you downloaded version with installer, just click on the installer file, it will guide you through the whole process and download all required files and libraries.
  6. After installation or unzip, if you want to run it, simply click on Computator.NET.exe (or Computator.NET shortcut on desktop if you had chosen installer) in whatever location you had chosen for it.

  • Windows (.NET Framework): Build status Build status
  • Linux (Mono and .NET Core): Build Status
  • IDE: Visual Studio 2015
  • InstallShield 2015 LE needed to build Installer project
  • Visual Studio 2015 Enterprise needed to build and run CodedUI tests
  • This repo supports Fork & Pull Model, you can do any useful changes and when you are done make a pull request. If your work is of good quality, it will be included in main branch.
  • List of things to do is updated constantly, you can view it here: TODO file. Choose wisely because some of those things are way harder than it looks.
  • List of known bugs (often with little or no reasonable solutions) is here: BUGS file.
  • Our unit tests coverage is small, partly because of the fact that there is good chunk of UI code here. Still I am afraid that there are lots and lots of not found bugs. If you want to help us fix those bugs, first try to catch them by writing good unit tests.
  • If you have found ANY bugs or you think something might be bug please report it in issues as fast as you can. Any help with testing / finding bugs is greatly appreciated.

What shortcut do you use to write in exponent, just like in gif presentation?

LShift+6 (^), just like it is listed in Edit menu from where you can also activate / deactivate writing in exponent without using this shortcut. Writing in exponent

How can I solve equations / do my homework using Computator.NET?

Computator.NET is numerical software that aims to provide functionality similar to Matlab and Mathematica. But it certainly isn't full Computer Algebra System, at least not yet. You can solve some equations by using 'Numerical calculations' tab and 'Function root' operation. Depending on the equation, different methods work better or worse. Solving equations using numerical calculations Alternatively, you can always solve equations graphically, simply by looking at the chart. solving equations graphically
