# Pi (Ramanujan's formula) Calculator

## Calculates circular constant Pi using the Ramanujan-type formula. | ||

The calculation ends when two consecutive results are the same. The accuracy of π improves by increasing the number of digits for calculation. In 1914, the Indian mathematician Ramanujan discovered the formula for computing Pi that converges rapidly. In 1987, Chudnovsky brothers discovered the Ramanujan-type formula that converges more rapidly. |
