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.
Math.js is a comprehensive mathematics library for JavaScript that provides a wide range of mathematical functions and capabilities. It allows you to perform complex mathematical operations, including algebraic expressions, matrix operations, statistical calculations, and more. Math.js supports both numerical and symbolic computations, making it suitable for a variety of mathematical applications.
Both Big.js and Math.js are popular npm packages in the JavaScript community. However, Math.js has a larger user base and wider adoption compared to Big.js.
Use Cases
Big.js is primarily focused on providing arbitrary-precision arithmetic capabilities. It is commonly used for handling and manipulating large numbers with precision. Math.js, on the other hand, is a more comprehensive math library that offers a wide range of mathematical functions and operations, including arithmetic, algebra, calculus, statistics, and more.
Functionality
Big.js is solely focused on providing a constructor for arbitrary-precision decimal arithmetic. It allows you to perform operations on numbers with arbitrary precision and avoid common precision errors. Math.js, on the other hand, provides a much broader range of mathematical functions and operations, making it suitable for more advanced math-related tasks.
Size
Big.js is a lightweight library with a small footprint, making it suitable for projects with limited resources or those that only require arbitrary-precision arithmetic. In comparison, Math.js is a more feature-rich library and, as a result, has a larger file size.
Ease of Use
Big.js offers a simple and straightforward API, making it easy to learn and use. It directly extends the JavaScript Number object, allowing you to perform arithmetic operations with ease. Math.js provides a comprehensive API with a large number of functions and options, which may require more time and effort to learn and fully utilize.
Dependencies
Big.js has no external dependencies, making it lightweight and easy to integrate into projects. Math.js, on the other hand, has several external dependencies, as it provides a wide range of mathematical operations and functionalities. This may increase the complexity of the project setup and introduce additional dependencies.
