Underscore Pi (2017)

• quietbritishjim 8y ago
  M_PI is not part of the C standard (it is part of Posix) so the title is awkward.
  • jgtrosh 8y ago
    I agree it's awkward, but not because of M_PI being non-standard. If history had lead to pi being defined in standard C, this code would still have been interesting. The title is awkward because it talks more about M_PI than about the content of the article.

      I agree that the code is interesting. It was specifically the HN title I was talking about, which is not even the title of the original article. Sorry if I wasn't clear. Anyway, it's been updated now.

  We changed the title from "Underscore Pi – when M_PI from math.h is too mainstream; IOCCC winning entry". This is a fine HN submission, but please don't rewrite titles to editorialize! https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html

    Could you maybe add something about it being an IOCCC winner back in? (I generally read the comments first to decide if I want to read the article, and I wasn't going to bother reading this until I saw it had something to do with the IOCCC)

  Unfortunately, this doesn't seem to work in Clang because it doesn't support the -traditional-cpp flag. Make sure that you're actually using GCC if you're following along!

  In all its glory: #define _ -F<00||--F-OO--; int F=00,OO=00;main(){F_OO();printf("%1.3f\n",4.*-F/OO/OO);}F_OO() { _-_-_-_ _-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_ _-_-_-_ } Fierce! Unhinged! Cromulent! Kickass!
