Mathf.Epsilon

설명

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.

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 &amp;&amp; a <= b + Mathf.Epsilon)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
