Fractional Approximations of Pi

After reading the American Scientist article, On the Teeth of Wheels, which describes the intricate interplay between pure and applied mathematics, and how clock makers independently developed mathematical methods to approximate gear ratios that were not feasibly made (such as representing gear ratios that were two primes with other gear ratios that were close in value), I decided to write a program to find fractional approximations of Pi. A couple of minutes searching google brought me to an existing fractional approximations of pi page, which attempted to find decimal approximations using an iterative approach, which turned out to be very slow. However since the code was open source, I decided to modify for my own uses. The stern-brocot method pretty much changes the O(n²) to about O(1) for the calculation of successive values.

You can get several versions of the source:
