Computer determination of pi

How can a computer be used to determine pi? Is it hard to understand? I
know all the good approximations but how do you write a program to find pi?
One of the best general articles related to the approximation of pi appeared
in *Scientific American* Feb 1988, pp 112-118. Very readable and can be
applied to your favorite programming language.
The methods given in the *Scientific American* article are based on the idea
that a transcendental number may be obtained as the limit of a sequence. An
algorithm based on Gregory's series of 1671 is presented and is, perhaps,
the most "friendly," but unfortunately takes an enormous amount of computer
