Just out of interest, did you need this?

This is a part of int/fraction delimiter's in different locales issue.
The problem is ru locale and probably some others.
In this locale comma is a delimiter between int and fraction parts of numbers.
So it's better to have another delimiter in that case.
Also I'm going to fix latitude/longitude to use corresponding delimiter between int and fraction parts of numbers
