Either one halfway nullifies the original proposal. The whole point of this issue is that $\tau$ is the basic mathematical constant related to circle, (and if $\pi$ is temporarily ever needed, the latter is the one that should be described in terms of the former, i.e, $\pi := \tau / 2$). Expressing $\tau$ in terms of $\pi$ goes counter to this. P.S. I have had the same idea as the $\tau$ proponents since when I was a high school student. I believe I am among the countless people, if not the majority, in this respect. ---------------------------------------- Feature #17496: Add constant Math::TAU https://bugs.ruby-lang.org/issues/17496#change-89881 * Author: jzakiya (Jabari Zakiya) * Status: Open * 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/ Unsubscribe:
