John Wallis (1616-1703) discovered a method for calculating the value of by finding the area under the quadrant of a circle. By finding that area, one can find the value of Pi. Wallis, through a long series of interpolations and inductions derived what is now known as Wallis' Formula:- Pi/2=(2*2*4*4*6*6*8*8*...)/(1*3*3*5*5*7*7*9*...) . This branch of programs calculates Pi for a given number of terms. The first version is in simple C, while the second uses inline assembly.
