Subject: [ruby-core:102039] [Ruby master Feature#17496] Add constant Math::TAU
Date: Tue, 12 Jan 2021 22:38:57 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-89891.20210112223856.11075@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-17496.20201231192740.11075@ruby-lang.org
Issue #17496 has been updated by universato (Yoshimine Sato).
FYI
https://processing.org/reference/TAU.html
Processing may not be a general purpose language, but it has `TAU` and `TWO_PI` on its core.
Processing has `TAU` since 2013.

In this paper τ is used in the Gaussian density function.

Feature #17496: Add constant Math::TAU
https://bugs.ruby-lang.org/issues/17496#change-89891
* 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. :-)
