Module oracle 

Oracle decimal conversion utilities.

Different oracle providers use different decimal precisions:

• Chainlink: 8 decimals for most feeds, 18 for some
• Pyth: Variable precision (exponent-based)
• RedStone: 8 decimals
• Band Protocol: 18 decimals

This module provides utilities for normalizing and converting between different oracle decimal formats.
