A058291: Continued fraction expansion of

2 π

,

(2 π = 6.283185...)

.

     

6 +  1 3 +  1 1 +  1 1 +  1 7 +  1 2 +  1 146 +  1 ⋱

On the argument that

τ = 2 π

is a more important constant than

π

, there is a campaign going on to have today acknowledged as “Tau Day” (like March 14 is sometimes called “Pi Day”). However, neither celebration is official.
