As far as i know, you can't input multiple arguments separated by commas in the /math command, only simple mathematical.. questions. As such, i believe adding support to decimal comma as an alternative to a decimal dot should be possible, and it would be nice, small quality of life improvement for many non-USA/UK PS! users - not having to think about using a different decimal separator/ not having to correct yourself all the time. Of course, only if it's something that's simple to implement.
