Do you know how many academic papers that uses tau as the circle constant have been published so far? How can anyone ever empirically answer these question? And why should they be *"the"* deciding factor? Have you done any research to answer these questions? Have you read the ``Tau Manifesto``? https://tauday.com/tau-manifesto Have you seen the ``Tau`` videos, like the Numberphile one? https://youtu.be/83ofi_L6eAo Every year there is a growing body of work promoting|using ``Tau``, and more languages including it. I don't think I can give you anymore of an objective, rational, and logical reason than these sources (with others). Like I said, this seems to ultimately be a philosophical|religious issue, and you're just not believers yet. Maybe in time hopefully you will be, but you must find your own way to acceptance, because others already have. Let's hope 2021 will be a better new year. Happy New Year! ---------------------------------------- Feature #17496: Add constant Math::TAU https://bugs.ruby-lang.org/issues/17496#change-89679 * Author: jzakiya (Jabari Zakiya) * Status: Rejected * Priority: Normal ---------------------------------------- Excuse me if this has been brought up before. This is a simple proposal to add the math constant ``Math::TAU`` = 2*``Math::PI``. See: https://tauday.com/ ``TAU`` has been included in a growing number of languages (Rust, Python3, Julia, et al), and this would add Ruby to that list, and make it even cooler. :-) -- https://bugs.ruby-lang.org/
