--- Comment #2 from Berni44 <bugzilla at bernis-buecher.de> ---
Meanwhile 

writef("%.2,f", 1234567.89);

does this grouping. Result: "1,234,567.89" It does not support a locale though.
And if I should guess, it will never do, because that would make the functions
non pure. A possible approach would probably be, to add a special module for
localization that calls writef and modifies the result according to the locale.
