Mathf.Round

설명

Returns f rounded to the nearest integer.

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.

public class ExampleClass : MonoBehaviour
{
    // Use this for initialization
    void Start()
    {
        // Prints 10
        Debug.Log(Mathf.Round(10.0f));

        // Prints 10
        Debug.Log(Mathf.Round(10.2f));

        // Prints 11
        Debug.Log(Mathf.Round(10.7f));

        // Prints 10
        Debug.Log(Mathf.Round(10.5f));

        // Prints 12
        Debug.Log(Mathf.Round(11.5f));

        // Prints -10
        Debug.Log(Mathf.Round(-10.0f));

        // Prints -10
        Debug.Log(Mathf.Round(-10.2f));

        // Prints -11
        Debug.Log(Mathf.Round(-10.7f));

        // Prints -10
        Debug.Log(Mathf.Round(-10.5f));

        // Prints -12
