The number π is a mathematical constant that is the ratio of a circle's circumference to its diameter. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes romanticized as "pi".

Being an irrational number, π cannot be expressed exactly as a ratio of any two integers (fractions such as 22/7 are commonly used to approximate π but no fraction can be its exact value).In fact, pi has been calculated to over two quadrillion decimal places and still there is no pattern.
