> I think I’ll just continue to define Tau myself rather then import this package. Maybe there’s some elaborate argument why it should be “tau ~ 2pi” but for my uses, it’s just 2pi. tau = 2pi Cool to know about mod2pi. Didn’t know it was in the base library, because I had no idea there was a name for this function, the code for it is well, interesting: [https://github.com/JuliaLang/julia/blob/c6da87ff4bc7a855e217856757ad3413cf6d1f79/base/math.jl#L801-L987](https://github.com/JuliaLang/julia/blob/c6da87ff4bc7a855e217856757ad3413cf6d1f79/base/math.jl#L801-L987) Guess this is why I’d never call myself …

The discussion of Tau has arrived numerous times on here!

There is a package for it 😃 [GitHub - JuliaMath/Tau.jl: A Julia module providing the definition of the circle constant Tau (2π)](https://github.com/JuliaMath/Tau.jl)
