is the number of collisions made (in ideal conditions, perfectly elastic with no friction) by an object of mass m initially at rest between a fixed wall and another object of mass b 2N m, when struck by the other object. [1] (This gives the digits of π in base b up to N digits past the radix point.)
The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [ 1 ] [ 2 ] [ 3 ] On an expression or formula calculator , one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
The bill was nearly passed by the Indiana General Assembly in the U.S., and has been claimed to imply a number of different values for π, although the closest it comes to explicitly asserting one is the wording "the ratio of the diameter and circumference is as five-fourths to four", which would make π = 16 ⁄ 5 = 3.2, a discrepancy of ...

Let be the number of digits to which is to be calculated. Let be the number of terms in the Taylor series (see equation 2). Let be the amount of time spent on each digit (for each term in the Taylor series). The Taylor series will converge when:
The case features many design elements from 1970s HP calculators such as the ground-breaking HP-65, including a black case with silver-striped curved sides, slope-fronted keys, and gold and blue shift keys. The faceplate is metal, bonded to the plastic case. The key legends are printed, rather than the double-shot moulding used in the vintage ...
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number π appears in many formulae across mathematics and physics .
