JavaScript => static function Approximately(a: float, b: float): bool;
C# => static bool Approximately(float a, float b);

Description 描述

Compares two floating point values if they are similar.

比较两个浮点数值，看它们是否非常接近。

Due to floating point imprecision it is not recommended to compare floats using the equal operator. eg. 1.0 == 10.0 / 10.0 might not return true.

由于浮点数值不精确，不建议使用等于来比较它们。例如，1.0==10.0/10.0也许不会返回true。

JavaScript:

if (Mathf.Approximately(1.0, 10.0/10.0))
	print ("same");

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Example() {
        if (Mathf.Approximately(1.0F, 10.0F / 10.0F))
            print("same");
 
    }
}
