## What it is
A PHP library for arbitrary-precision arithmetic providing BigInteger, BigDecimal, and BigRational classes. It automatically uses the fastest available calculator implementation (GMP, BCMath, or a pure-PHP fallback).

## Use cases
- do exact math with very large integers in PHP
- handle money calculations without floating-point errors
- work with arbitrary precision decimal numbers
- compute with rational numbers and fractions
- avoid integer overflow in PHP calculations

## When to choose
- you need exact arithmetic beyond PHP's native int/float limits
- you want a well-tested, production-ready precision math library with optional GMP/BCMath acceleration

## When to avoid
- you only need standard floating-point math
- you're on PHP < 8.2 and can't use an older release branch

## Facets
- artifact type: library
