The number π is a mathematical constant, the ratio of a circle‘s circumference to its diameter, approximately equal to 3.14159. It has been represented by the Greek letter “π” since the mid-18th century though it is also sometimes spelled out as “pi“.

Being an irrational number, π cannot be expressed exactly as a common fraction. Consequently its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed although no proof of this has yet been discovered. Also, π is a transcendental number – a number that is not the root of any nonzero polynomial having rational coefficients. This transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straight-edge.

Fractions such as 22/7 and other rational numbers are commonly used to approximate π.

For thousands of years mathematicians have attempted to extend their understanding of π… – Wikipedia
