# Zero-Floating-Point Money & Currency Math Engine
A lightweight, high-precision financial arithmetic utility for TypeScript and JavaScript applications.
## ⚠️ The Problem with JavaScript Numbers
JavaScript numbers use IEEE-754 binary floating-point representation. This leads to subtle but catastrophic rounding errors in billing and ledger systems:
```javascript
0.1 + 0.2; // 0.30000000000000004 ❌
19.99 * 100; // 1998.9999999999998 ❌
