public static float Epsilon;

Description

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.

Additional resources: Mathf.Approximately.

using UnityEngine;

public class Example : MonoBehaviour { // 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.

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