A small, fast, easy-to-use library for arbitrary-precision decimal arithmetic
bignumber.js
v9.1.2(about 1 year ago)
BigNumber.js is a JavaScript library that provides arbitrary-precision arithmetic for working with large numbers that exceed the limitations of standard JavaScript numbers. It allows precise calculations with integers and floating-point numbers, ensuring accuracy in mathematical operations. BigNumber.js is commonly used in financial applications, cryptography, and any scenario where precision is crucial.
Both Big.js and Bignumber.js are popular npm packages for handling arbitrary precision arithmetic in JavaScript. Bignumber.js has been around for longer and has a larger following, but Big.js also has a significant user base and is widely used.
Functionality
Both packages provide similar functionality for performing arithmetic operations with arbitrary precision numbers. They support basic arithmetic operations like addition, subtraction, multiplication, and division, as well as more advanced operations like exponentiation, square root, and trigonometric functions.
API and Usage
Bignumber.js provides a more feature-rich API with a wide range of methods for various mathematical operations. It also has support for chaining operations and formatting options. Big.js, on the other hand, has a simpler API with fewer methods but is still sufficient for most use cases.
Performance
In terms of performance, Big.js is known to be faster and more efficient than Bignumber.js. Big.js is designed to provide a lightweight and optimized solution for arithmetic operations, while Bignumber.js is more focused on providing a comprehensive set of features.
Dependencies
Big.js has no external dependencies and is a standalone library, making it easier to integrate into projects. Bignumber.js, however, has a dependency on the 'decimal.js' library, which adds an additional layer of functionality and complexity.
Community and Maintenance
Both packages have active communities and are well-maintained. Bignumber.js has a larger community and has been around for longer, which means it has a more extensive ecosystem and community support. Big.js, while newer, still benefits from regular maintenance and updates from its developer.
