Interesting, will check the site out. Apropos: I had blogged this a while ago: Bhaskaracharya and the man who found zero: http://jugad2.blogspot.in/2010/06/bh

  And here is one of his books, the Lilavati: http://en.wikipedia.org/wiki/Lilavati http://en.wikipedia.org/wiki/Lilavati I noticed this at that page: "Bhaskara II gives the value of pi as 22/7 in the book but suggest a more accurate ratio of 3927/1250 for use in astronomical calculations." I also remembered reading somewhere that some ancient Indians had a simple formula for pi that was somewhat accurate; take the first 3 odd positive integers, twice each, as one single number, split it down the middle, and divide the right half by the left half, i.e. 113355 => 355/113 = ~pi. So I checked, using Python: $ python >>> from math import pi >>> pi 3.141592653589793 >>> print 3927.0/1250 3.1416 >>> print 355.0/113 3.14159292035 The approximation that uses 113355 matches pi (from Python) upto 6 decimal places.
