Question

JavaScript => static var Epsilon: float;
C# => static float Epsilon;

Description 描述

A tiny floating point value (Read Only).

一个很小的浮点数值。（只读）['epsiln]

The smallest value that a float can have different from zero.

大于0的最小浮点数。

With the following rules:

具有以下规则：

- 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.

任意数与Epsilon的之间值将导致在任意数发生截断误差。

See Also: Mathf.Approximately.

JavaScript:

// Compares two floating point numbers and return true if they are the same number.
//比较两个浮点数,如果它们是相同的数返回true，
// See also Mathf.Approximately, which compares floating point numbers so you dont have
// to create a function to compare them.
//参见Mathf.Approximately，在那里比较浮点数因此你不必创建一个函数来比较它们
 
function isEqual(a: float, b : float) {
	if(a >= b-Mathf.Epsilon && a <= b + Mathf.Epsilon)
		return true;
	else
		return false;
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    bool isEqual(float a, float b) {
        if (a >= b - Mathf.Epsilon && a <= b + Mathf.Epsilon)
            return true;
        else
            return false;
    }
