Approximately equal operator is available now (see Options dialog to set the accuracy):
I see the "Approximately equal" operator accuracy varies from 0 to 15. What does this value actually represent?

Hi! 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.
considering that the "accuracy operator" parameter that regulates "approximately equal" is unique, wouldn't it be appropriate that it is defined in percentage terms?
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?
Regarding that.. I think "precision operator" more appropriately reflects the intended purpose.

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.

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/forum/yaf_postst21614_Inline-division.aspx
About 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.

how to input else if? I use SMathStudioDesktop.1_0_8206.Mono
how to input else if? I use SMathStudioDesktop.1_0_8206.Mono
In the placeholders of the if() function type an "argument separator" symbol (comma or semicolon, usually)
The if without else will improve alot the readability of many scripts, thank you Andrey.

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.

Hi. 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.

You don't provide enough maths for attempting to doctor.
You may get inspired from the double Simpson integrator.
Please, don't hesitate ... Jean

The question is why in the stable version integrals are calculated without problems, but in the new one it gives an error in the same places?

In other words, you declare a bug.
Designers need the document for doctoring.
... doctor since which SS version ?
1.0.8151.26932 OK
1.0.8206.25180 NFG
Yes, I'm reporting a bug. In version 1.0.8151.26932, dimensionless integrals with limits in the form of arbitrary functions are calculated correctly. In version 1.0.8206.25180, such integrals are not evaluated. The error "x/y - undefined" is returned.

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.
