Don't. If user expressed his wish to format numbers with
a decimal comma instead of point by setting LC_NUMERIC, you
should not enforce decimal point. And other functions like
scanf() use/expect decimal comma too in such a locale
anyway.
If you didn't format the numbers for user interface, but to
serialize them to some data file for example, you could use
g_ascii_dtostr() or g_ascii_formatd(), but for user
interface this would be arrogant.
