The following are programs I wrote a while back to take the actual value of PI (calculated elsewhere) or any other number desired, and find increasingly closer integer fractions/ratios that approximate that value.  The first is written in C and requires LIBGMP (free open source software).  The second is written in PIKE (free open source software).
