### Examples

```csharp
using UnityEngine;
using UnityEditor;

    bool showRoundPosition = true;
    bool showRoundRotation = true;

    [MenuItem("Examples/Round positions-rotations")]

    {

        window.Show();
    }

    void OnGUI()
    {

            DoRoundPosition();
        EditorGUILayout.EndToggleGroup();
        showRoundRotation = EditorGUILayout.BeginToggleGroup("Round Rotation", showRoundRotation);
        if (GUILayout.Button("Round Rotation!"))
            DoRoundRotation();
        EditorGUILayout.EndToggleGroup();
    }

    void DoRoundPosition()
    {
        foreach (Transform t in Selection.transforms)
            t.localPosition = new Vector3(Mathf.Round(t.localPosition.x),
                Mathf.Round(t.localPosition.z),
                Mathf.Round(t.localPosition.y));
    }

    void DoRoundRotation()

                    Mathf.Round(t.eulerAngles.y / 45f) * 45f,
                    Mathf.Round(t.eulerAngles.z / 45f) * 45f));
    }

    void OnFocus()
    {
        if (EditorPrefs.HasKey("ShowRoundPosition"))
            showRoundPosition = EditorPrefs.GetBool("ShowRoundPosition");
        if (EditorPrefs.HasKey("ShowRoundRotation"))

        EditorPrefs.SetBool("ShowRoundRotation", showRoundRotation);
    }

    void OnDestroy()
    {
        EditorPrefs.SetBool("ShowRoundPosition", showRoundPosition);
        EditorPrefs.SetBool("ShowRoundRotation", showRoundRotation);
    }
