Currency.js is a lightweight JavaScript library for handling currency and money formatting, conversion, and arithmetic operations. It provides a simple and intuitive API for working with monetary values, allowing developers to easily format currencies, perform calculations with automatic precision handling, and convert between different currencies.
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.
Both Currency.js and Decimal.js are popular npm packages for working with numbers and currencies. Currency.js has gained popularity for its simplicity and ease of use, while Decimal.js is known for its precision and advanced mathematical operations.
Functionality
Currency.js is specifically designed for working with currencies and provides features like currency conversion, formatting, and arithmetic operations with automatic precision handling. Decimal.js, on the other hand, is a general-purpose arbitrary-precision decimal arithmetic library that can handle complex mathematical operations with high precision.
Precision
Decimal.js is known for its high precision and accuracy in decimal calculations. It allows you to specify the desired precision and rounding modes for your calculations. Currency.js, while it provides basic precision handling for currency calculations, may not be suitable for scenarios that require extremely high precision.
Ease of Use
Currency.js is designed to have a simple and intuitive API, making it easy to work with currencies. It provides convenient methods for formatting, parsing, and performing arithmetic operations on currencies. Decimal.js, on the other hand, has a more extensive API and may require a deeper understanding of mathematical concepts for complex calculations.
Dependencies
Currency.js has minimal dependencies and is lightweight, making it suitable for projects with strict size constraints. Decimal.js has a few more dependencies and a larger codebase due to its advanced mathematical capabilities.
Community Support
Both Currency.js and Decimal.js have active communities and are well-maintained. Currency.js has a larger user base and more community contributions, which can be beneficial for finding resources and getting support. Decimal.js, while it may have a smaller community, is known for its precision and reliability.
