pi is a universal constant. It is a transcendental number which is a special kind of irrational number. It cannot be expressed as a terminating or repeating decimal, nor as a ratio of integers or surds. There are various ways in which pi can be calculated and expressed. Commonly used approximations are 22/7, 3.14, 3.14159. Last year pi was calculated to 5 trillion digits although 40 digits are thought to be sufficient to calculate the angle subtended on earth by a hydrogen atom at the far end of the known universe!

It is many orders of magnitude greater than the number of elementary particles in the known universe.
