Option to disable digit grouping.

[m-fessler]

Problem Statement
Digit grouping cannot be switched off.

Evidence or User Insights
I've been reading the same question multiple times in various forums for years.
People are then usually recommended to change the behavior system-wide or even use calc.exe from an older Windows version - neither is optimal.

Proposal
A simple on/off option in the app settings, like calc.exe from Windows 7 had.

Goals
A user could thus quickly and easily switch the number grouping on or off regardless of the system-wide setting.

Requested Assignment
I'm just suggesting this idea. I don't want to (and can't) implement it.

Thank you and best regards,
Martin
