Fermat.js

Fermat.js is a powerful mathematics, statistics and geometry library for JavaScript. It contains everything from number theory to random numbers, expression parsing and linear algebra classes. It was developed for Mathigon.org, an award-winning mathematics education project.

Features

• Arithmetic: nearlyEquals(), toWord(), toFraction(), …
• Combinatorics: factorial(), binomial(), permutations(), subsets()
• Complex numbers: Complex()
• Cryptography: caesarCipher(), vigenereCipher(), letterFrequency()
• Expression parsing: Expression()
• Geometry: Point(), Line(), Polygon(), Circle(), Angle(), as well as methods for geometric properties, projections, intersections and much more
• Matrices: matrix.product(), matrix.determinant(), matrix.inverse(), …
• Number theory: gcd(), isPrime(), generatePrime(), goldbach(), …
• Numeric: bisect(), integrate()
• Random: random.shuffle(), random.binomial(), random.normalPDF(), …
• Regression: regression.linear(), regression.coefficient(), …
• Statistics: mean(), variance(), linearRegression(), …
• Units: convert(), define()
• Vector: Vector()

Usage

First, install fermat.js from NPM using

npm install @mathigon/fermat --save

Fermat.js uses ES6 imports. While some browsers and platforms now support this feature, we recommend using a transpiler such as Babel or Rollup. Make sure that you configure your compiler to correctly resolve these imports. For Rollup, we recommend using the rollup-plugin-node-resolve plugin.

Now, simply import all functions and classes you need, using

import { Complex, gcd } from '@mathigon/fermat'
