DigitsOfPie

A Swift-based calculator for the digits of Pi (π), currently hardlimited to a maximum of 10,000 — although this can be easily changed in the storyboard slider limits. This demo uses a Machin-based Pi calculation, except that it uses the Integer package's infinite-sized integers to get as many digits as we want. It still computes the formula: pi = 4 * (4 * arccot(5) - arccot(239)). The user interface is very simple with a slider to control the number of pi digits. Calculations are performed in a background task so the slider motion is not affected during the calculations.

UInt128

SwiftMathDemo

SwiftMathDemo demonstrates the use of SwiftMath using SwiftUI. The same code runs on Macs, iPhones, and iPads. Code is entirely written in Swift. The MathView.swift file provides a SwiftMath interface to SwiftUI.

CQuadReals

Doubles

A quad-double number (QDouble) is an unevaluated sum of four IEEE double precision numbers, capable of representing at least 212 bits of significand. Algorithms for various arithmetic operations (including the four basic operations and various algebraic and transcendental operations) are presented. A Swift implementation of these algorithms is attached, along with its interfaces.
