Mathf.RoundToInt 四舍五入到整数

static function RoundToInt (f : float) : int

Description描述

Returns f rounded to the nearest integer.

返回 f 指定的值四舍五入到最近的整数。

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。

public class example : MonoBehaviour {
	public void Awake() {
		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));
	}
}

// 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));
