This file describes how pi is computed by the program in 'pi.c' (see the utils subdirectory). Basically, we use Machin's formula, which is what everyone in the world uses as a simple method for compu

/* * pi.c * * Compute pi to an arbitrary number of digits. Uses Machin's formula, * like everyone else on the planet: * * pi = 16 * arctan(1/5) - 4 * arctan(1/239) * * This is pretty effe
