Number.EPSILON — usage in tolerance comparison

📖 Usage Example

// Use EPSILON to compare floats safely
0.1 + 0.2 === 0.3   // → false (floating-point issue)
Math.abs(0.1 + 0.2 - 0.3) < Number.EPSILON   // → true

Use Number.EPSILON as a tolerance threshold when comparing floating-point numbers that may differ by tiny rounding errors.

Tolerance Comparison with EPSILON

Use Number.EPSILON as a tolerance to determine if two numbers are close enough to be treated as equal.
