Pi, in mathematics, is the ratio of the circumference of a circle to its diameter. Because pi is irrational (not equal to the ratio of any two whole numbers), its digits do not repeat, and an approximation such as 3.14 or 22/7 is often used for everyday

The importance of pi has been recognized for at least 4,000 years. A History of Pi notes that by 2000 B.C., "the Babylonians(巴比伦人) and the Egyptians (at least)were aware ofthe existence and significance of the constant π," recognizing that every circle has the same ratio of circ...

The record for calculating Pi is with 5 trillion digits! The closest fraction to represent Pi is found to be 227. But even this is not completely accurate. The first calculations of Pi were done in the Babylonians in 2000 BC who determined it as 3.125. Further, the Ancient Egyptians came...
