In particular, the digit sequence of π is conjectured to satisfy a specific kind of statistical randomness, but to date, no proof of this has been discovered. The digits appear to be randomly distributed. Still, fractions such as 22/7 and other rational numbers are commonly used to approximate π. It is also called Archimedes' constant.īeing an irrational number, π cannot be expressed as a common fraction (equivalently, its decimal representation never ends and never settles into a permanently repeating pattern). It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi". Originally defined as the ratio of a circle's circumference to its diameter, it now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics. The number π () is a mathematical constant.
