[swift-evolution] Extend FloatingPoint with tau!

[David Waite]

-1

Tau, unlike pi, is not a commonly understood mathematical constant.  Even in the realm of mathematics, tau is used to represent multiple concepts and other constants, such as the golden ratio. 

Finally, tau is easily computed from pi and should not result in a loss of precision. This makes it an excellent candidate for addition via an extension for third party code which desires it and understands what "tau" means in their domain
