Abstract
In this paper, we present an improved continued fraction approximation of the Wallis ratio. This approximation is fast in comparison with the recently discovered asymptotic series. We also establish the double-side inequality related to this approximation. Finally, some numerical computations are provided for demonstrating the superiority of our approximation.
