Describe the feature

In most areas of the world numbers are written like so:

2,312.25

Not:

2.312,25

That is, comma first, period second.

There should be at the very least an option to reverse the placement.

Further reasoning for this is that my debts to me looks like I only owe €25.32 cents. Not €25,325...

Why is this feature important?

There is the possibility of misunderstanding balances.

Additional context, screenshots, and relevant links

Comma and period should be replaced eg. in the case of all these amounts.
