Re: [Boost-users] [boost] Ann: Floating Point Utilities Review starts today

3) C++ locale facets: these will read and write non-finite numbers in a portable and round-trippable way: that is not otherwise possible with current C++ std library implementations. These are particularly useful for number-serialisation for example.

There are quite a few test failures from these, I'm hoping these are related to these facets rather than the underlying utility code: MSVC-8 (debug) Running 8 test cases... nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed nonfinite_num_facets/legacy_test.cpp(120): error in "legacy_test": check (isnan) (b11) failed nonfinite_num_facets/legacy_test.cpp(138): error in "legacy_test": check ss.rdst ate() == std::ios_base::eofbit failed *** 12 failures detected in test suite "Master Test Suite" MSVC-8 (release + SSE2) Running 8 test cases... nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/basic_test.cpp(167): error in "basic_test": check ss.str() == s failed nonfinite_num_facets/basic_test.cpp(182): error in "basic_test": check (signbit) (b2) failed nonfinite_num_facets/basic_test.cpp(184): error in "basic_test": check (signbit) (b4) failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed nonfinite_num_facets/lexical_cast_test.cpp(86): error in "lexical_cast_test": ch eck lexical_cast(a9) == s9 failed nonfinite_num_facets/lexical_cast_test.cpp(87): error in "lexical_cast_test": ch eck lexical_cast(a10) == s10 failed *** 30 failures detected in test suite "Master Test Suite" Perhaps perversely, VC8 in release mode, but without the /arch:SSE2 option passes all the tests. Intel-10.1 has similar failures (except in SSE2 mode!), so this may be iostream's related. Full review to follow.... John.
