Decimal.js is a JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. It provides accurate and reliable arithmetic operations on decimal numbers, avoiding common floating-point errors. Decimal.js is particularly useful for financial and scientific applications where precision is crucial.
Dinero.js is a modern JavaScript library for working with monetary values and currencies. It provides a simple and intuitive API for performing arithmetic operations, formatting currencies, and handling currency conversions. Dinero.js is designed to be immutable and safe for financial calculations, ensuring precision and consistency in monetary computations.
Both Decimal.js and Dinero.js are popular npm packages in the JavaScript community. Decimal.js has been around for longer and has a larger user base, while Dinero.js has gained popularity more recently due to its focus on handling monetary values.
Functionality
Decimal.js is a library for arbitrary-precision decimal arithmetic, providing precise calculations for decimal numbers. It offers a wide range of mathematical operations and formatting options. Dinero.js, on the other hand, is specifically designed for handling monetary values and provides features like currency conversion, formatting, and rounding according to different financial rules.
Ease of Use
Both libraries have a straightforward API and are easy to use. Decimal.js provides a comprehensive set of methods for performing mathematical operations, while Dinero.js focuses on providing a simple and intuitive API for working with monetary values.
Performance
Decimal.js is known for its excellent performance in handling decimal arithmetic operations. It utilizes optimized algorithms to ensure fast and accurate calculations. Dinero.js also performs well in most scenarios, but its focus on monetary calculations may result in slightly slower performance compared to Decimal.js for general arithmetic operations.
Flexibility
Decimal.js is a standalone library that can be used in both browser and Node.js environments. It does not have any dependencies and can be easily integrated into any project. Dinero.js, on the other hand, is built specifically for use with JavaScript frameworks like React and Vue.js. It provides additional features like formatting and localization tailored for working with monetary values.
Community and Documentation
Both Decimal.js and Dinero.js have active communities and are well-documented. Decimal.js has been around for longer, so it has a larger community and more extensive documentation. Dinero.js, being a more specialized library, has a smaller but growing community and provides comprehensive documentation with examples and guides specifically focused on handling monetary values.
