Fight!

Popularity

Both BigNumber.js and Decimal.js are popular npm packages for working with arbitrary-precision decimal arithmetic. BigNumber.js has been around for longer and has a larger user base, but Decimal.js has also gained popularity in recent years.

Precision and Accuracy

Both libraries offer high precision and accuracy for decimal arithmetic. However, Decimal.js provides more advanced features for controlling precision, rounding, and handling of special values like NaN and Infinity.

Functionality

Both libraries provide a comprehensive set of mathematical operations and functions for working with decimal numbers. BigNumber.js has a slightly larger feature set and supports additional operations like bitwise operations and trigonometric functions.

Ease of Use

Both libraries have a similar API and are easy to use. They provide methods for creating, manipulating, and performing calculations with decimal numbers. Decimal.js has a more intuitive and consistent API, making it slightly easier to work with.

Performance

In terms of performance, BigNumber.js is generally faster than Decimal.js for basic arithmetic operations. However, Decimal.js offers better performance for more complex operations and has optimizations for handling large numbers.

Documentation and Community Support

Both libraries have well-documented APIs and active communities. BigNumber.js has more extensive documentation and a larger community, which means there are more resources and examples available. Decimal.js also has good documentation and community support, but it may be slightly less extensive.
