5//! Deterministic fixed-point arithmetic for financial computation.
6//!
7//! This crate provides [`Decimal`], a 128-bit decimal type with configurable
8//! rounding modes designed for financial calculations that must produce
9//! identical results across all platforms.
10//!
11//! # Oracle Integration
12//!
13//! The [`oracle`] module provides utilities for working with different oracle
14//! decimal formats (Chainlink, Pyth, etc.) commonly used in DeFi applications.
