Big.js is a JavaScript library that provides arbitrary-precision decimal arithmetic. It allows you to perform precise calculations with decimal numbers, avoiding the rounding errors that can occur with native JavaScript number handling. Big.js supports a wide range of mathematical operations, including addition, subtraction, multiplication, division, and more.
Dinero.js is a JavaScript library for working with monetary values and currencies. It provides a simple and intuitive API for performing common financial calculations like addition, subtraction, multiplication, division, and currency conversion. Dinero.js supports various formatting options for displaying monetary values in different locales and currencies.
Big.js is a widely used package for arbitrary-precision decimal arithmetic and has been around for a longer time. Dinero.js, on the other hand, is a newer library specifically designed for handling monetary values in JavaScript. While Big.js has a larger user base, Dinero.js has been gaining popularity in the JavaScript community.
Functionality
Big.js provides a comprehensive set of mathematical operations for working with arbitrary-precision decimal numbers. It focuses on precision and accuracy and is not specific to monetary values. Dinero.js, on the other hand, is designed specifically for handling monetary values and provides features like formatting, currency conversion, and currency arithmetic out-of-the-box.
Ease of Use
Both libraries have a straightforward API and are easy to use. Big.js provides a set of simple methods for performing mathematical operations on decimal numbers. Dinero.js, being tailored for financial calculations, has a more specialized API that aligns well with monetary concepts, making it easier to work with currencies and perform monetary calculations.
Performance
In terms of performance, Big.js is known for its capability to handle large numbers with precision. It focuses on accuracy at the expense of some performance. Dinero.js, on the other hand, optimizes for performance and provides efficient calculations specifically for monetary values. It leverages internal optimizations to balance precision and performance for financial calculations.
Compatibility
Both Big.js and Dinero.js are compatible with Node.js and modern web browsers. They can be used in both backend and frontend applications, allowing for versatile usage in various JavaScript environments.
Community Support
Big.js has been widely adopted and has a large community of users, which means you can find a lot of resources, examples, and community support. Dinero.js, although newer, also has an active community and is quickly gaining popularity. Both libraries have good documentation and offer support through their respective GitHub repositories.
