[#note-P0067] P0067: ``std::(to|from)_chars`` for integrals has been available since version 7.0. ``std::to_chars`` for ``float`` and ``double`` since version 14.0 ``std::to_chars`` for ``long double`` uses the implementation for ``double``. 44 .. [#note-P0607] P0607: The parts of P0607 that are not done are the ``<regex>`` bits. 45 .. [#note-P0154] P0154: This is currently not implemented for clang because clang does not implement the required macros. 46 .. [#note-P0452] P0452: The changes to ``std::transform_inclusive_scan`` and ``std::transform_exclusive_scan`` have not yet been implemented. 47 48.. _issues-status-cxx17: 49 50Library Working Group Issues Status 51==================================== 52 53.. csv-table:: 54 :file: Cxx17Issues.csv 55 :header-rows: 1 56 :widths: auto 57
