An infamous number that is well known world wide, is pi. The reason being, is merely the fact that pi is a very unique number. Pi continues to go on forever, but never repeats a number, or has any significance in number patterns. Some people had a great talent in memorizing the most numbers from pi as possible. Others don't care much for the number at all. Pi's equivalent fraction is 22/7, simply because if you take 22, and divide it by 7, then you have pi. Pi is an irrational number, because it isn't a terminal(stops at one point), and it doesn't repeat the same numbers. Sometimes instead of using Pi itself, most prefer to use the fraction instead.
     . Starting around the 15th century, new algorithms based on infinite series revolutionized the computation of π, and were used by mathematicians including Madhava of Sangamagrama, Isaac Newton, Leonhard Euler, Carl Friedrich Gauss, and Srinivas Ramanujan. In the 20th and 21st centuries, mathematicians and computer scientists discovered new approaches that – when combined with increasing computational power – extended the decimal representation of π to, as of late 2011, over 10 trillion (1013) digits. Scientific applications generally require no more than 40 digits of π, so the primary motivation for these computations is the human desire to break records, but the extensive calculations involved have been used to test supercomputers and high-precision multiplication algorithms.
