Hello all.

I'm about to introduce Significant figures mode for numeric results.

The question is: it is logical enough to implement such a UI? So that Significant figures mode is located under Decimal places...
For me it looks very convenient (the one who want to tune accuracy will definitely open Decimal places menu + there is no need to have separate menu level), but what do you think?

Best regards, Andrey Ivashov.

I was just thinking about this today! I'm glad to hear you're implementing this functionality.

I think the decimal places menu is a logical place to put the option.

Will there be an option from the toobar menu as well? Tools -> Options -> Calculation to make Significant Figures mode default?

Yes, exactly in the place you have mentioned.

I would probably use significant figures mode as default. And I vote for toolbar buttons: one to increase the number and one to decrease it, action depending on what mode is selected.

These buttons would only be visible if the cursor is on a region with numeric results.

Me as well, that's the only thing I understand.
There was upon a time 0 was defined e-12.
As it looks, some brilliants IEEE decided 0 can be anything.
Whatever: it takes only 15 significant figures input

Hello Andrey,

Great idea!
I would also use significant figures mode as default.

The decimal places menu is for me too the most logical place to put the option.

Thanks again for all your work you put in Smath!

Like Mathcad: double click on the result for a drop down menu.
By same token: round off to 0 result like 1.23456e-16
... the col operator <,> would be great too
The Floor/Ceil are so gorgeous 6179 !
Martin 'LinSolve' in the f(x) menu too,

Thanks in advance ... Jean
