It's locale dependent, so make sure LC_NUMERIC is set to a locale that
formats in that style (e.g. da_DK, and presumably your own). In order
to use the locale stuff in C or C++, you need to call setlocale to set
the locale stuff up.
In C:
#include <locale.h>
setlocale(LC_ALL, "");
In C++:
#include <locale>
std::locale::global(std::locale(""));
The latter should imply the former, but I'm not totally convinced
(I've seen some odd problems when using C date functions which stopped
when I added a setlocale() call).
Just to confuse things further, in C++ it's possible to define your
own locale facets to customise this yourself. Jossuttis' "The C++
Standard Library" will tell you how.
Regards,
Roger
