New Beta SMath Studio 1.0.8206 is available!Tiny, powerful, free mathematical program with WYSIWYG editor and complete units of measurements support. It provides numerous computing features and rich user interface translated into about 40 different languages. Application also contains integrated mathematical reference book. Changes introduced in current buildImprovements- if(..) function extended to support any number of arguments more or equal to 2;
- Approximately Equal operator implemented (Options dialog extended with an appropriate setting; button added to the Boolean toolbox);
- Defined Integral supports units now;
- Rendering of the text improved in program dialogs;
- Electron-volt (k, M, G, T) unit added;
- Sleep function added allows to suspends the current thread for the specified amount of time specified in milliseconds;
- Proxy settings implemented.
Corrections- Numeric calculations with units corrected in cases when final result is equal to zero.
Miscellaneous- Startup of Desktop version is made faster in the environments where access to printer is slow;
- High DPI support improved;
- Displaying of the previews improved in Insert Function dialog;
- Offline login logic corrected;
- Settings dialog refactoring;
- SMath LLC code certificate issued and included into repository.

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 13 time(s). |

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. 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.

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 10 time(s).
