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.

A possible approach would probably be, to add a special module for localization that calls writef and modifies the result according to the locale.

A way to keep purity with locales would be to pass the locale into the functions, e.g.

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

Sure, but it would make the functions much more complicated - for example think of different digit shapes used in some areas of the world or even printing from right to left (what's the minus-flag supposed to do in that case?)... I'd prefer to have localization in a wrapper in a different module.

I'm closing this, because the support for grouping exists and localization is a different thing. I opened a new one for this: Issue 21819.
