--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-05-18 20:47:19 UTC --- In the ISO C++ Standard which we are implementing, the semantics of setprecision and numeric output in general, is specified in terms of printf behavior. In this specific implementation, in fact, printf is actually, literally, used. Thus, if you have reasons to believe that 5798.12 is incorrect you should report the issue to the glibc maintainers, not the libstdc++ maintainers, because printf on Linux systems is part of glibc.
