It has been represented by the Greek letter \"π\" since the mid-18th century, though it is also sometimes spelled out as \"pi\" (/paɪ/).Being an irrational number, π cannot be expressed exactly as a fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern)." ] ,
