• 🔧 The --fix option on the command line can automatically fix some of the problems reported by this rule.

📖 Rule Details

This rule aims to enforce the use of Number.EPSILON instead of other ways to represent the smallest floating point epsilon.

Number.EPSILON provides several advantages over manual calculations:

• Clarity of intent: Immediately obvious that you're using the machine epsilon value
• Precision: Provides the exact IEEE 754 double-precision floating-point epsilon value
• Maintainability: Avoids hardcoded values that might be incorrect or imprecise
• Readability: Makes floating-point comparison code more understandable
