Mathf.Epsilon

説明

ごくわずかな浮動小数点の値を返す（読み取り専用）。

0 との差分を持っている最小の値。

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