Hi Vitaly.I should have told you this one long time ago. In some previous version I could use "," as decimal separator (eg 2,5 for 2.5). It doesn't work anymore.
Yes, some time ago we tried to use your current locale-specific decimal separator, but unfortunately it didn't work for everyone and sometimes people ended up with not being able to enter decimal point at all. That's why we finally switched to point as the only way to enter decimals. It is not perfect, but much more predictable.
Hope this helps.
