Two Vector3 values comparison using coroutine

hi, everyone.
i'm doing two rotation(vector3) values comparison, but sometime it is not matched. and i'm using coroutine.
here is my code

Code (CSharp):

1. if (!Mathf.Approximately(targetObjectRotation.x, currentObjectRotation.x))
2.             currentObjectRotation.x += (differenceObjectRotation.x / 30f);
3. else
4.             isCorrectX = true;
5.  
6. if (!Mathf.Approximately(targetObjectRotation.y, currentObjectRotation.y))
7.             currentObjectRotation.y += (differenceObjectRotation.y / 30f);
8. else
9.             isCorrectY = true;
10.  
11. if (!Mathf.Approximately(targetObjectRotation.z, currentObjectRotation.z))
12.             currentObjectRotation.z += (differenceObjectRotation.z / 30f);
13. else
14.             isCorrectZ = true;

sometime one of three value is incorrect. so occur infinity loop. how do i that?

 

i found this problem's solution. i'm just added code

Code (CSharp):

1. if (!Mathf.Approximately(targetObjectRotation.x, currentObjectRotation.x) && Mathf.Abs(targetObjectRotation.x - currentObjectRotation.x) > 0.5f)

i don't know it is helpful or correct method.
