{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"_Py_c_sum, _Py_c_diff, etc - were removed from Python.h","articleBody":"See #106339 and #106320.  But these functions are documented as public: https://docs.python.org/3/c-api/complex.html#complex-numbers-as-c-structures\r\n\r\nI think c38c666 should be partially reverted and ``_Py_c_abs`` - documented.\r\n\r\nOn another hand, quick github search shows very little examples of using above functions.  See also https://github.com/python/cpython/issues/106320#issuecomment-1633302147.  So, in a long term I propose to deprecate this API and related functions (PyComplex_FromCComplex/PyComplex_AsCComplex).  Who knows, maybe someday we could use ``\u003ccomplex.h\u003e``...\r\n\r\n\u003c!-- gh-linked-prs --\u003e\r\n### Linked PRs\r\n* gh-112021\r\n* gh-112107\r\n\u003c!-- /gh-linked-prs --\u003e\r\n","author":{"url":"https://github.com/skirpichev","@type":"Person","name":"skirpichev"},"datePublished":"2023-11-13T05:24:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/112019/cpython/issues/112019"}
