Infinite series, like the Leibniz formula for π, offered a more efficient way to approximate its value. The development of calculus provided new tools for calculating π, leading to significant advancements. Even so, these methods were computationally intensive and required significant manual effort.
The advent of computers revolutionized the calculation of π. Practically speaking, modern algorithms, such as the Chudnovsky algorithm and the Bailey-Borwein-Plouffe (BBP) formula, make use of the power of computing to calculate trillions, even quadrillions, of digits of π. These algorithms are significantly more efficient than previous methods, drastically reducing the time required to compute increasingly precise values. The BBP formula, for instance, allows for the calculation of specific digits of π without calculating the preceding digits, a remarkable feat in computational mathematics.
