"," instead of "." in German language

[twoxx]

Hello!

German language uses "," as decimal separator instead of "."

for example: "3,2" instead of "3.2".

text2num is wirting this correctly BUT

other softwares (for example node red) is using "." as decimal separator.

So other software is thinking that "3,2" is not a number, other software is always thinking that this is a String or there are two numers separated with ","... and so on....

can you make something like a "parameter" while using german languag to decide if the output should be "3,2" or "3.5" ?
