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.
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.
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 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.
