Math.js is an extensive math library for JavaScript and Node.js that provides a flexible expression parser with support for symbolic computation.
The library solves the problem of performing complex mathematical operations across diverse data types in JavaScript environments. It works by offering a unified interface that handles numbers, big numbers, complex numbers, fractions, units, matrices, and arrays, allowing operations to mix these types seamlessly. The expression parser evaluates mathematical expressions as strings, and the tool includes a large set of built-in functions and constants. It also supports symbolic computation and chained operations, making it suitable for both simple calculations and sophisticated mathematical workflows.
Developers should choose this tool if they need to work with multiple numeric types in a single codebase or require expression evaluation capabilities beyond JavaScript's native Math library. It suits projects ranging from scientific computing to financial applications that demand precision with big numbers or complex number support. The library runs on any ES2020-compatible JavaScript engine, including Node.js and all major browsers, and can be used as a command-line application. It is easily extensible, allowing developers to add custom data types and functions to the core system.
The project maintains active development with regular updates to its codebase. The architecture is designed around a core principle of enabling calculations with mixed data types, using a two-ingredient solution that allows different numeric types to interact naturally within matrices and expressions. The tool is well-documented with comprehensive guides, examples, and API documentation available on its website.
