Changing decimal point (locale?)

[thomasa88]

I'm outputting data in Swedish numeric format, where the decimal point is "," (and the thousands separator is " ").

I would like to be handle to have the smart decimal point alignment, but for "," instead of ".".

My numbers are input at strings as I'm internally using my own fixed point: "100,25" (But I can change to "100.25" for input.)
