7257	Boost.Test alters and does not restore ostream precision after any Test macro	Paul A. Bristow	Raffi Enficiaud	"Boost.Test alters and does not restore ostream precision after any Test macro.

    std::cout.precision(17);

    std::streamsize precision1 = std::cout.precision(); // 17

    BOOST_TEST_MESSAGE("""");  or any BOOST_TEST_* calls.

    std::streamsize precision2 = std::cout.precision(); // 6  (default)

    BOOST_CHECK_EQUAL(precision1, precision2); // expect both 17

This means that it is necessary to reset precision after every call to a BOOST_TEST_* macro, which is a tiresome and unexpected feature.
