The number Ï is a mathematical constant, the ratio of a circle 's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter  Ï  since the mid-18th century, though it is also sometimes spelled out as  pi  (/paÉª/). Being an irrational number, Ï cannot be expressed exactly as a fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern).
