📖 Rule Details

This rule aims to enforce the use of Math.PI instead of literal number representations of π (pi).

Using Math.PI instead of hardcoded numeric literals improves:

• Readability: Makes the intention clear that you're using the mathematical constant π
• Maintainability: Centralized definition reduces the risk of typos
• Precision: Math.PI provides the most accurate representation available in JavaScript
• Consistency: Standardizes how mathematical constants are used across your codebase
