> But the test program does demonstrate a real problem, and that is the
> formatting of infinity when the stream precision is greater than 7. It looks
> as though the num_put facet inserts the string "inf\0\0ity" into the stream
> rather than "inf".
> $ cat u.cpp && make u && ./u | od -c
> #include <cassert>
> #include <iostream>
> #include <sstream>
> int main () {
> std::ostringstream s;
> s.precision (8);
> s << 1 / 0.0;
> std::cout << s.str () << '\n';
> assert (s.str () == "inf");
