JavaScript => static function RoundToInt(f: float): int;
C# => static int RoundToInt(float f);

Description 描述

Returns f rounded to the nearest integer.

返回浮点数 f 进行四舍五入最接近的整数。

If the number ends in .5 so it is halfway between two integers, one of which is even and the other odd, the even number is returned.

如果数字末尾是.5，因此它是在两个整数中间，不管是偶数或是奇数，将返回偶数。

JavaScript:

// Prints 10
Debug.Log(Mathf.RoundToInt(10.0));
// Prints 10
Debug.Log(Mathf.RoundToInt(10.2));
// Prints 11
Debug.Log(Mathf.RoundToInt(10.7));
// Prints 10
Debug.Log(Mathf.RoundToInt(10.5));
// Prints 12
Debug.Log(Mathf.RoundToInt(11.5));
// Prints -10
Debug.Log(Mathf.RoundToInt(-10.0));
// Prints -10
Debug.Log(Mathf.RoundToInt(-10.2));
// Prints -11
Debug.Log(Mathf.RoundToInt(-10.7));
// Prints -10
Debug.Log(Mathf.RoundToInt(-10.5));
// Prints -12
Debug.Log(Mathf.RoundToInt(-11.5));

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Example() {
        Debug.Log(Mathf.RoundToInt(10.0F));
        Debug.Log(Mathf.RoundToInt(10.2F));
        Debug.Log(Mathf.RoundToInt(10.7F));
        Debug.Log(Mathf.RoundToInt(10.5F));
        Debug.Log(Mathf.RoundToInt(11.5F));
        Debug.Log(Mathf.RoundToInt(-10.0F));
        Debug.Log(Mathf.RoundToInt(-10.2F));
        Debug.Log(Mathf.RoundToInt(-10.7F));
        Debug.Log(Mathf.RoundToInt(-10.5F));
        Debug.Log(Mathf.RoundToInt(-11.5F));
    }
}
