And one more factoid in case anybody cares:
Pi (π), the 16th letter of the Greek alphabet, is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference is equal to pi times the diameter (c = πd). No matter how large or small a circle is, pi will always work out to be the same number.
Pi is an irrational number, which means that it is a real number with nonrepeating decimal expansion, thus it goes on forever without arriving at a zero at the end. Some math fanatics have been interested in seeing how far it can be extended. The Guiness World Record for reciting the most digits of pi belongs to Lu Chao of China, who has recited pi to more than 67,000 decimal places. The Pi-Search Page website has calculated it (with the help of a computer program) to 200 million digits.
