# Quartic.js [![Build Status][travis-image]][travis] [![devDependency Status][david-image]][david]

> JavaScript library for solving quartic equations.

## Install

```bash
$ npm install @skymaker/quartic 
```

### Usage

Pass an array of the 5 coefficients of equation to solve, from the `x^4` term down to the constant term.

The results are returned as [Math.js][mathjs] complex number objects, with `re` and `im` properties that hold the real and imaginary part of the complex root respectively.

```js
var quartic = require('quartic');

//Solve 5x^4 + 4x^3+ 3x^2 + 2x + 1
var roots = quartic.solve(5,4,3,2,1); 

console.log(roots);
```

## Get the code

```bash
$ git clone https://github.com/lavelle/quartic
$ cd quartic
$ npm install
$ npm test
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
