Mathf.Approximately 近似

static function Approximately (a : float, b : float) : bool

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。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		if (Mathf.Approximately(1.0F, 10.0F / 10.0F))
			print("same");

	}
}

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