## Math.Tau

I have just uploaded a new package to Hackage which defines the constant $\tau$. Now if you wish to use $\tau$ in your program you can just cabal install tau and then import Math.Tau (tau), and be assured that you are using only the highest-quality definition of this fundamentally important constant.

I’m happy to see that you had to foresight to specify that this package would only work with base < 10. As you presumably well know, the base 11 release is scheduled to reconfigure the universe so that the circumference/radius is the more orderly integer 6.

• Brent says:

Indeed. It will also export tau, so at that point we will instead need a pi package to export the constant pi = 3.

2. Harley says:

Interesting, I already have such a package. Simply import the Pi package and let t = 2Pi. :-)

3. Chris Dornan says:

From which we can speculate that TeX ~= Math.Tau/2. (And perhaps on their authors passing this could become a true equation.)
