In this situation you will +// need to cast a human eye over the error rates reported and make +// a judgement as to whether they are acceptable. Either way please +// report the results to the Boost mailing list. Acceptable rates of +// error are marked up below as a series of regular expressions that +// identify the compiler/stdlib/platform/data-type/test-data/test-function +// along with the maximum expected peek and RMS mean errors for that +// test. +// + +void expected_results() +{ + // + // Define the max and mean errors expected for + // various compilers and platforms. + // + const char* largest_type; +#ifndef BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS + if(boost::math::policies::digits >() == boost::math::policies::digits >()) + { + largest_type = "(long\\s+)?double"; + } + else + { + largest_type = "long double"; + } +#else + largest_type = "(long\\s+)?double"; +#endif + // + // Linux special cases, error rates seem to be much higer here + // even though the implementation contains nothing but basic + // arithmetic? + // + if((std::numeric_limits::digits <= 64) + && (std::numeric_limits::digits != std::numeric_limits::digits)) + { +#ifndef BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS + add_expected_result( + ".*", // compiler + ".*", // stdlib + ".*", // platform + "double", // test type(s) + ".*", // test data group + ".*", 10, 5); // test function +#endif + } + add_expected_result( + ".*", // compiler + ".*", // stdlib + "linux.*|Mac OS|Sun.*", // platform + largest_type, // test type(s) + ".*", // test data group + ".*", 40000, 1000); // test function + add_expected_result( + ".*", // compiler + ".*", // stdlib + "linux.*|Mac OS|Sun.*", // platform + "real_concept", // test type(s) + ".*", // test data group + ".*", 40000, 1000); // test function + add_expected_result( + "GNU.*", // compiler + ".*", // stdlib + "Win32.*", // platform + largest_type, // test type(s) + ".*", // test data group + ".*", 40000, 1000); // test function + add_expected_result( + "GNU.*", // compiler + ".*", // stdlib + "Win32.*", // platform + "real_concept", // test type(s) + ".*", // test data group + ".*", 40000, 1000); // test function + add_expected_result( + ".*", // compiler + ".*", // stdlib + "IBM Aix", // platform + largest_type, // test type(s) + ".*", // test data group + ".*", 5000, 500); // test function + add_expected_result( + ".*", // compiler + ".*", // stdlib + "IBM Aix", // platform + "real_concept", // test type(s) + ".*", // test data group + ".*", 5000, 500); // test function + + // + // Catch all cases come last: + // + add_expected_result( + ".*", // compiler + ".*", // stdlib + ".*", // platform + largest_type, // test type(s) + ".*", // test data group + ".*", 4000, 500); // test function + add_expected_result( + ".*", // compiler + ".*", // stdlib + ".*", // platform + "real_concept", // test type(s) + ".*", // test data group + ".*", 4000, 500); // test function + + // + // Finish off by printing out the compiler/stdlib/platform names, + // we do this to make it easier to mark up expected error rates. + // + std::cout << "Tests run with " << BOOST_COMPILER << ", " + << BOOST_STDLIB << ", " << BOOST_PLATFORM << std::endl; +} + +BOOST_AUTO_TEST_CASE( test_main ) +{ + BOOST_MATH_CONTROL_FP; + +#ifndef BOOST_MATH_BUGGY_LARGE_FLOAT_CONSTANTS + test_spots(0.0F, "float"); +#endif + test_spots(0.0, "double"); +#ifndef BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS + test_spots(0.0L, "long double"); + test_spots(boost::math::concepts::real_concept(0.1), "real_concept"); +#endif + + expected_results(); + +#ifndef BOOST_MATH_BUGGY_LARGE_FLOAT_CONSTANTS + test_laguerre(0.1F, "float"); +#endif + test_laguerre(0.1, "double"); +#ifndef BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS + test_laguerre(0.1L, "long double"); +#ifndef BOOST_MATH_NO_REAL_CONCEPT_TESTS + test_laguerre(boost::math::concepts::real_concept(0.1), "real_concept"); +#endif +#else + std::cout << "The long double tests have been disabled on this platform " + "either because the long double overloads of the usual math functions are " + "not available at all, or because they are too inaccurate for these tests " + "to pass." << std::endl; +#endif + +} + + + -- cgit v1.2.3
