Brick Math
A PHP library for arbitrary-precision arithmetic with support for integers, decimals, and rational numbers.
What is Brick Math?
Brick\Math is a PHP library that provides arbitrary-precision arithmetic, enabling accurate calculations with numbers of any size without the limitations of native PHP types. It solves the problem of handling large integers, precise decimals, and rational numbers (fractions) in PHP, where native types like int and float have size and precision constraints. The library emphasizes reliability, performance, and immutability, automatically leveraging extensions like GMP or BCMath when available for faster operations.
PHP developers working on applications requiring precise mathematical calculations, such as financial systems, scientific computing, cryptography, or any scenario where handling very large numbers or exact decimal representations is critical. It is also suitable for developers needing to avoid floating-point inaccuracies or integer overflow issues in PHP.
Developers choose Brick\Math over alternatives because it offers a comprehensive, type-safe, and immutable API for arbitrary-precision integers, decimals, and rational numbers in one library, with automatic performance optimization via GMP or BCMath. Its focus on exception safety, flexible rounding modes, and seamless serialization across different PHP environments provides a robust solution for precise arithmetic without external dependencies beyond optional extensions.
