This number's hexadecimal representation can be computed using the BBP spigot algorithm.
This number's hexadecimal representation can be computed using the BBP spigot algorithm. By applying the method of exhaustion, Archimedes bounded this value above and below using a 96-gon. This number is the square of the Gaussian integral. A sixth of the square of this number equals the sum of the reciprocals of the perfect squares. This number is one-fourth the number of steradians in a sphere. This irrational number is the period of the tangent function and also the area of the unit circle. For 10 points, name the ratio of the circumference and diameter of a circle, whose value is approximately 3.14.
