Jsfinance is a project mainly written in JavaScript, it's free.
Example JavaScript code for financial mathematics calculations
This repository contains example code in JavaScript to explain and demonstrate financial calculations. It follows the programming projects suggested in Mark Joshi's "The Concepts and Practice of Mathematical Finance".
These examples are featured in videos on my YouTube video channel. http://www.youtube.com/user/NathanWhitehead
Please let me know what you think or what else you would like to see!
The examples are designed to work in both Node and in the browser. Code uses a single global variable, Finance, as a namespace. Test suites have "_test" at the end. Code that is specific to the browser ends with "_ui".
