A053003: Simple continued fraction for Gauß's constant \scriptstyle \frac{2}{\pi} \int_{0}^{1} \frac{1}{\sqrt{1 - x^4}} dx \,

1 + \frac{1}{5 + \cfrac{1}{21 + \cfrac{1}{3 + \cfrac{1}{\ddots\qquad{}}}}} \,

This is the reciprocal of the arithmetic-geometric mean of 1 and \scriptstyle \sqrt{2} \,. It was on May 30, 1799 that Carl Friedrich Gauß discovered the integral for this number shown above. (For its decimal expansion, see A014549.)
