Tenho usado Mathcad por muitos anos, como estudante, como pesquisador e como engenheiro químico. Mas Mathcad se tornou inviável há alguns anos. É formidável ter uma ferramenta tão boa quanto ele de forma gratuita ou a curtos muito baixos como o SMath! Obrigado LLC SMath e Andrey Ivashov!

I've used this software for several years and can not use anything else for work. I'm a mechanical Engineer and use this for any calculations I do.
1) To show and check my work
2) to set values and write descriptions so I can reuse my formulas for other projects.
This is better than any calculator.
Thank you Smath for such a great software.

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)

Thank you very much for your work and for you programm. I have just started to use it, but already see that it's a wonderful tool for engineers.

Although it lacks some of mathcad's possibilities, it is undoubtedly an excellent spreadsheet for engineering.

Great tool for all engineers. It's very user-friendly and has lots of functionalities that can be further extended by installing plug-ins (it takes just a few clicks, no need for tedious file manipulations). SMath can operate on units, perform symbolic calculations and many more. Also, it has very clear interface and all formulas can be entered just like you would do on a piece of paper. What's more, the software has great community of people willing to help with various issues.

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).
