Hi

str2num has problems with nonstandard settings of decimal delimiter (komma) and function argument delimiter (semicolon). The error message indicates that the function tries to convert the internal argument separator (komma) to periods.

Best regards, Martin Kraska

Edit: Seems that the bug has been fixed:
[MATH lang=ENG]str2num(num2str(sys(1.2,2,2,1)))=sys(1.2,2,2,1)[/MATH]

Another issue with regional settings.

When a variable name or a function name created using default settings (decimals->period,separator->comma) contains a semicolon (maybe in the subscript or not), opening the file with different settings (decimals->comma,separator->semicolon) cause an "empty stack" error (and the file can't be opened).

No chances to fix this? It's critical when sharing worksheets based on norms like Eurocodes or similars...

I see the only way to fix it is to forbid semicolon symbol in variables/functions names. I'll do it.
I think instead I need to implement some common way to allow any characters to be used in names. But a bit later...

One of the most missed characters is the % sign (as a unit name, '%:0,01), in order to avoid ugly constructs like in the attachment.

mhhh... ok... I know, dot, comma and semicolon are special and sensible characters....
There are some unicode characters very similar ‚ ; I don't know if could be useful for the development of these exceptions (as dirty idea when an user is typing the name of the variable/function, Smath can convert "on the fly" the keyboard comma and semicolon input into this characters...)


thank you for any your effort
