WebBeautiful formula of π (continued fraction). π is an irrational number. This means that π can not be written as a ratio of two integers: π ≠ n m for any integers n, m. However, π can be written as an infinite series of nested fractions, known as continued fraction. There are several known continued fractions that are equal to π.
