public static var Epsilon: float;
public static float Epsilon;


A tiny floating point value (Read Only).

The smallest value that a float can have different from zero.

With the following rules:

- anyValue + Epsilon = anyValue
- anyValue - Epsilon = anyValue
- 0 + Epsilon = Epsilon
- 0 - Epsilon = -Epsilon

A value Between any number and Epsilon will result in an arbitrary number due to truncating errors.

See Also: Mathf.Approximately.

// Compares two floating point numbers and return true if they are the same number.
// See also Mathf.Approximately, which compares floating point numbers so you dont have 
// to create a function to compare them.

function isEqual(a: float, b : float) { if(a >= b-Mathf.Epsilon && a <= b + Mathf.Epsilon) return true; else return false; }

public class ExampleClass : MonoBehaviour { bool isEqual(float a, float b) { if (a >= b - Mathf.Epsilon && a <= b + Mathf.Epsilon) return true; else return false; } }
