Actually, I ran into what I would call a bug.
using namespace boost::locale;
std::string dbl = boost::lexical_cast<std::string>(3.14);
std::cout << dbl << std::endl;
My language settings currently use ',' as decimal separator as do the
settings for the french (Canada) language settings.
The commented out version outputs "3,14000000001". This is what I would
expect to happen. The boost::locale version outputs "3.14000000001".
It looks to me like the punctuation stuff isn't being set up correctly.
The as::number thing doesn't do anything either. Only locale::format
catches on and does it right.
I managed to get it going by hacking around a bit. Not sure if what I'm
doing is actually close to anything that might be what it should be...
std::locale::global(std::locale(loc0, loc1, std::locale::all));
I'd expect that the delimiters and such would be set up the same in both
cases and this merge attempt of mine shouldn't be necessary.
