Crate precision_core 

Deterministic fixed-point arithmetic for financial computation.

This crate provides Decimal, a 128-bit decimal type with configurable rounding modes designed for financial calculations that must produce identical results across all platforms.

Oracle Integration

The oracle module provides utilities for working with different oracle decimal formats (Chainlink, Pyth, etc.) commonly used in DeFi applications.
