## What it is
A PHP library implementing Fowler's Money pattern as a value object for safe monetary calculations, avoiding float rounding errors by using string-backed big integers. It includes currency repositories, money formatting, allocation, and exchange rate support via Swap.

## Use cases
- store and calculate monetary values without float errors
- convert between currencies with exchange rates
- split an amount into parts without losing cents
- format money amounts for display with intl
- work with ISO currencies in PHP
- handle very large monetary values with big integers

## When to choose
- you're building a PHP application dealing with payments, billing, or prices
- you need exact arithmetic on monetary values
- you need currency conversion or allocation logic

## When to avoid
- your project is not in PHP
- you only need simple display formatting without arithmetic
- you need a full accounting or ledger system rather than a value object

- artifact type: library
