```
using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        // let Unity show these as (1.0, 2.0, 3.0)
        Vector3 vector = new Vector3(1, 2, 3);
        Debug.Log(vector.ToString());

// unity sadly decides (1.2, 5.7, 9.0)
        vector = new Vector3(1.234f, 5.678f, 9.012f);
        Debug.Log(vector.ToString());

// but we can show this using format - 3 numbers after the decimal point
        // (1.234, 5.678, 9.012)
        Debug.Log(vector.ToString("F3"));

// now let's create some longer numbers
        vector = new Vector3(1.0f / 3.0f, -Mathf.PI, Mathf.Exp(-2.0f));

// we get (0.333333, -3.141593, 0.135335)
        Debug.Log("fractional part is 6: " + vector.ToString("F6"));

// note how F8 cannot display these numbers as we want
        // (0.33333330, -3.14159300, 0.13533530)
        Debug.Log("fractional part is 8: " + vector.ToString("F8"));
    }
