[jira] Created: (STDCXX-461) Error in formatting of infinity
Error in formatting of infinity
--------------------------------
Key: STDCXX-461
URL: https://issues.apache.org/jira/browse/STDCXX-461
Project: C++ Standard Library
Issue Type: Bug
Components: 27. Input/Output
Reporter: Jeremy Dean
Priority: Minor
referrenced in e-mail thread:
http://mail-archives.apache.org/mod_mbox/incubator-stdcxx-dev/200706.mbox/ajax/%3c46801DBC.90909@roguewave.com%3e
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");
}

Here's a simplified test case:
$ cat t.cpp && gmake t && ./t

#include <sstream>
int main () {
std::ostringstream s;
s.precision (8);
const std::num_put<char> &np =
std::use_facet<std::num_put<char> >(s.getloc ());
np.put (std::ostreambuf_iterator<char>(s), s, ' ', 1 / 0.0);
assert (s.str () == "inf");
}
