Thanks for the info. I already knows it by grepping all LC_NUMERIC files
on my FreeBSD.

$ cat /usr/share/locale/hi_IN.ISCII-DEV/LC_NUMERIC
.
,
2;3

Futher analysis showed that

$ find /usr/share/locale/ -name LC_NUMERIC -exec cat {} \; | sort -u

,
-1
.
.
0;0
2;3
3;3

I have yet to dechiper -1 and 0;0. Presumably, it's no grouping at all.

Actually, it returns std::string. C counterpart returns char* which,
I believe, is faster.

C++ locales are unsupported on FreeBSD 6.1 RC #2. I will have to boot
knoppix to check how num_punct<>::grouping() works.
