It is the first non trivial convergent to the continued fraction of [[Acoustic pi|acoustic π]]. The next in the series is 333/106, a much more complex 53-limit interval. The difference between π and 22/7 is of only 0.697 cents. | It is the first non trivial convergent to the continued fraction of [[Acoustic pi|acoustic π]].
