Free for personal usage! Plans for Organizations are available!
Application can be easily extended based on your needs. Built-in Extensions Manager tool allows to get access to hundreds official and third-party resources of the following types: usage examples, plug-ins, SMath Viewer based applications, snippets, interface translations, interactive books, handbooks and tutorials.
This fantastic free alternative to Mathcad is going from strength to strength and I am really enjoying watching its progress. Andrey has produced something that is genuinely useful, multiplatform, fun to use and, most importantly of all, he listens to his users. Well worth a download.

Niezwykle przejrzyste narzędzie. Świetne do sprawdzenia czegoś na szybko, naturalne jak pisanie w zeszycie. Silna alternatywa dla MathCADa, zdecydowanie godny polecenia!

Any case of "if" statement is available now. Approximately equal operator is available now (see Options dialog to set the accuracy):

Hi Andrey,
I see the "Approximately equal" operator accuracy varies from 0 to 15. What does this value actually represent? |

It is an accuracy of the "Approximately equal" operator. F.e. if the accuracy is 0, then pi≈3, if 1, then pi≈3.1, if accuracy is set as 2, then pi≈3.14 etc. Best regards.

Hi Andrey, considering that the "accuracy operator" parameter that regulates "approximately equal" is unique, wouldn't it be appropriate that it is defined in percentage terms?

It's more than just the decimal place precision. approximately.sm (5kb) downloaded 14 time(s). |

Regarding that.. I think "precision operator" more appropriately reflects the intended purpose. |

Best regards. This is a nice new feature. Would it be possible to modify this value independent to regions? Adding another submenu to region right-click would be awesome. As in decimal places, exponential threshold, rounding choosing. Regards

Hi. About the new approximately equal operator, another way to introduce it could be introducing a general infix operator, like in Mathcad. This screen capture is from Mathcad 6 running in Windows 3.11: For work with units you just need to modify the rhs by abs( a-b ) < UnitsOf( a-b )*TOL (or maybe UoM). Notice that also can be a solution for another features requests, like this one about inline division: https://en.smath.com/for...614_Inline-division.aspxAbout the "Defined Integral supports units now" it is a major improvement, and while there will be many worksheets to update, it is a substantial and very welcome improvement. I do think that some kind of special announcement should be made. Also, if you plan to also modify solve and roots to accept drives, you may want to introduce the two improvements together in a future stable beta release. Finally, many thanks to you Andrey and to all the developers who collaborate with the plugins for this excellent program. Best regards. Alvaro. Edited by user 22 June 2022 04:20:57(UTC)

I hope you keep on developing this great software!
Thank you very much, it is easy and very efficient.
If someone could help you to bring it closer to a nice text editor, it would probably replace Word for many engineers and other scientists.

Great program for conducting engineering calculations. The ability to insert text blocks and pictures makes it perfect for both computation and communication of the results to colleagues.

Smath-Studio is a compelling mathematical application. It allows for quick and efficient symbolic and numerical calculations, making it a better alternative to MathCad, and Mathematica. The developers continue to add new features and functionality to this program regularly. I have been using this application for six months and love it. I tip my hat to the developers, well-done guys!

Thank you. But the problem is not because of eval(). She's somewhere deeper. My f3(x) and f4(x) limits are ainterp() of the table data.

Yes, I see that there are more than one issue with the double integration, even for some simple cases it is not sowed. Best regards. Alvaro.

It may be the XLS import ? Try NOT import as a stand alone system. It doesn't matter if there is an import from Excel or not. Proizvol'noe sechenie_no XLSX.sm (74kb) downloaded 11 time(s).
