Desktop OUR AFFILIATES THE ASSOCIATED PRESS TOKYO To most people, it's a funny-looking Greek letter that has something to do with circles. To Professor Yasumasa Kanada, however, pi is an obsession. Kanada and a team of researchers set a new world record by calculating the value of pi to 1.24 trillion places, project team member Makoto Kudo said yesterday. The previous record, set by Kanada in 1999, was 206.158 billion places. Figuring out pi to much more than about 1,000 decimal places serves little purpose in math or engineering, but researchers say it helps push computing power to a new level and can test the accuracy of supercomputers. "It's an enormous feat of computing not only for the sheer volume, but it's an advance in the technique he's using," said David Bailey, the chief technologist at the National Energy Research Scientific Computing Center at the Lawrence Berkeley National Laboratory in California.

    Extractions: Scientists today are using algorithms developed by mathematicians in the past to program high speed computers, yielding larger and larger calculations of . The advent of the computer has allowed to be calculated to over 6 billion digits. The first computer calculation of was made in September, 1949 on ENIAC (Electronic Numerical Integrator and Computer), using the Machin formula. It took 70 hours to calculate to 2,037 places. During the years that followed, it became a challenge to calculate the largest number of digits of , just as it had been in earlier times. In the years between 1980 and 1990, the calculation went from a number in the millions to one in the billions. The current record for the calculation of is over 6 billion digits and the current record holder is Yasumasa Kanada, who hopes to one day calculate to over ten billion places. In September and October, 1995, using the HITAC S-3800/480, Professor Yasumasa Kanada of the University of Tokyo calculated decimal digits of . He used the Borwein formula, a 4 th order convergent algorithm. For verification of the results the

On this page, I shall provide an overview of this extraordinary number: its history, properties, and its interesting facts. History of Pi Ancient History is perhaps the most famous ratio in mathematics. It is defined as the ratio between the circumference of a circle and its diameter. Throughout the ages, mathematicians have strived to find the value of . One of the earliest reference to was recorded in the Rhind Papyrus during the Egyptian Middle Kingdom, and was written by a scribe named Ahmes around 1650 BC. Ahmes began the scroll with the words: "The Entrance Into the Knowledge of All Existing Things", and made passing remarks that he composed the scroll "in likeness to writings made of old." Towards the end of the scroll, which comprises of various mathematical problems and their solutions, the area of a circle is found using a rough sort of It is interesting to note that the number is also indrectly quoted in the Bible. There is a little-known verse that reads
