Thanks Andrey Ivashov for this wonderful tool that you provided.
It is designed very well and the best opensource alternative to MathCAD available.

You should definitely try and use SMath Studio. This “one-man” project is really awesome. I can state, with no doubt, that every Mathcad user will be rather surprised.

I have been wishing for a sensible alternative to the free version of MathCAD for a long time. I find such software a crucial tool for writing technical-paper-style documents with live formulas and units carried throughout. I am so happy to have found SMath Studio as it is not just a completely free, fully featured alternative, but I find it to be much better in that it is tiny, is easier to use, has nice community support and has nice expandability by others (through plugins). It has features I've always wanted like setting of number of significant digits (not just number of decimal places), easier typing of subscripts, better plotting (via the X-Y Plot plugin), ability to include other SMath files (like my own units definitions), the very innovative and helpful "dynamic assistant", the ability to assign values to variables *after* the writing of a formula, no watermark across each page, and many other improvements that I have yet to discover. Since I am so pleased, I just donated $100 which I feel is a more reasonable amount for software like this. Thank you, Andrey!

Andrey has given us back the joy of Math that we experimented with Mathcad some thirty years ago, until PTC messed it all up. A fantastic achievement! And free! I am beginning to use it intensively to help my engineering students.

The functionality of the program can be expanded through the installation of plug-ins created by third-party developers and companies, as well as those prepared by the SMath LLC team. Most plug-ins are open source and can be modified if necessary.

Please note: - There are some known bugs with Worksheet scrolling - will be addressed soon;
- There are some UI issues on environment with high DPI (some Custom plug-ins may not be scaled correctly).
Please use the following to disable high dpi support if required:
To all developers: As you may notice starting from build 0.99.6955 SMath Studio supports high DPI and in order to scale Regions correctly we have to introduce new requirement: - Plug-in must use SMath.Drawing.Graphics instead of System.Drawing.Graphics everywhere.or - All Fonts created by the plug-in must have GraphicsUnit.Pixel specified as a unit and size must be multiplied by 96f / 72f in order to convert Points to Pixels.All existing plug-ins should be updated according to this requirement as everything looks ok while system is configured to have use 96 DPI, but in all other cases scaling of Fonts in plug-ins is incorrect. All modern platforms like iOS, Android, UWP have Pixel specified as a unit by default, so this issue appears on Windows machines only (we have it on Linux as well because of Mono). Please let me know in case of any related questions. If you are not able to perform changes by yourself - just let me know and I will update plug-ins by myself. Best regards, Andrey Ivashov.
