测试 每个小数值取100次

print(0.1);
LaTest3(0.1f, 0.1f);

print("Max:" + La.Max() + "|Min:" + La.Min() + "|AVG:" + La.Average() + "|Between:" + (La.Max() - La.Min()));

　　LaTest3函数

List<float> La;
    float[] LaTest3(float x, float y)
    {
        La = new List<float>();
        for (int i = 0; i < 100; i++)
        {
            La.Add(Mathf.PerlinNoise(x+(i), y + (i)));
        }
        return La.ToArray();
    }

　　

 

越接近0.5幅度越大，两边则越平缓

与整数无关，小数决定幅度。
