Rabinowitz and Wagon (in American Mathematical Monthly 102(3):195203, 1995) present a spigot algorithm for computing the digits of #. A spigot algorithm yields its outputs incrementally, and does not reuse them after producing them. Their algorithm is inherently bounded ; it requires a commitment in advance to the number of digits to be computed, and in fact might still produce an incorrect last few digits.
