bignumber.js - A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic

•    Javascript

---

A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. If a smaller and simpler library is required see big.js. It's less than half the size but only works with decimal numbers and only has half the methods. It also does not allow NaN or Infinity, or have the configuration options of this library.

node-bignum - Big integers for Node.js using OpenSSL

•    Javascript

---

Arbitrary precision integral arithmetic for Node.js using OpenSSL. This library is based on node-bigint by substack, but instead of using libgmp, it uses the builtin bignum functionality provided by OpenSSL. The advantage is that OpenSSL is already part of Node.js, so this library does not add any external dependency whatsoever.

BigInt - Arbitrary-precision arithmetic in pure Swift

•    Swift

---

This repository provides integer types of arbitrary width implemented in 100% pure Swift. The underlying representation is in base 2^64, using Array<UInt64>. This module is handy when you need an integer type that's wider than UIntMax, but you don't want to add The GNU Multiple Precision Arithmetic Library as a dependency.

proposal-bigint - Arbitrary precision integers in JavaScript

•    HTML

---

Thanks for help and feedback on this effort from Brendan Eich, Waldemar Horwat, Jaro Sevcik, Benedikt Meurer, Michael Saboff, Adam Klein, Sarah Groff-Palermo and others. BigInt is a new primitive that provides a way to represent whole numbers larger than 253, which is the largest number Javascript can reliably represent with the Number primitive.

javascript-bignum - Scheme arithmetic library for JavaScript

Scheme arithmetic library for JavaScript, https://github.com/jtobey/javascript-bignum. Copyright (c) 2010, 2011, 2012 John Tobey jtobey@john-edwin-tobey.org Copyright (c) 2009 Matthew Crumley email@matthewcrumley.com Licensed under the MIT license, file LICENSE. Big integer implementation based on javascript-biginteger, https://github.com/silentmatt/javascript-biginteger. The Scheme language supports "exact" arithmetic and mixing exact with inexact numbers. Several basic operations, including add, subtract, multiply, and divide, when given only exact arguments, must return an exact, numerically correct result. They are allowed to fail due to running out of memory, but they are not allowed to return approximations the way ECMAScript operators may.

DifferentialEquations.jl - Julia suite for high-performance solvers of differential equations

•    Julia

---

The well-optimized DifferentialEquations solvers benchmark as the some of the fastest implementations, using classic algorithms and ones from recent research which routinely outperform the "standard" C/Fortran methods, and include algorithms optimized for high-precision and HPC applications. At the same time, it wraps the classic C/Fortran methods, making it easy to switch over to them whenever necessary. It integrates with the Julia package sphere, for example using Juno's progress meter, automatic plotting, built-in interpolations, and wraps other differential equation solvers so that many different methods for solving the equations can be accessed by simply switching a keyword argument. It utilizes Julia's generality to be able to solve problems specified with arbitrary number types (types with units like Unitful, and arbitrary precision numbers like BigFloats and ArbFloats), arbitrary sized arrays (ODEs on matrices), and more. This gives a powerful mixture of speed and productivity features to help you solve and analyze your differential equations faster. For information on using the package, see the stable documentation. Use the latest documentation for the version of the documentation which contains the un-released features.

Geolib - Growing library to provide some basic geo functions

•    Javascript

---

Library to provide basic geospatial operations like distance calculation, conversion of decimal coordinates to sexagesimal and vice versa, etc. Takes 2 or 4 arguments. First 2 arguments must be objects that each have latitude and longitude properties (e.g. {latitude: 52.518611, longitude: 13.408056}). Coordinates can be in sexagesimal or decimal format. 3rd argument is accuracy (in meters). So a calculated distance of 1248 meters with an accuracy of 100 is returned as 1200 (accuracy 10 = 1250 etc.). 4th argument is precision in sub-meters (1 is meter presicion, 2 is decimeters, 3 is centimeters, etc).

HdrHistogram - A High Dynamic Range (HDR) Histogram

•    Java

---

HdrHistogram supports the recording and analyzing sampled data value counts across a configurable integer value range with configurable value precision within the range. Value precision is expressed as the number of significant digits in the value recording, and provides control over value quantization behavior across the value range and the subsequent value resolution at any given level.
