RTS Camera wiggle approaching to clamped borders

Questions & Answers
1

I made borders for my RTS Camera using Mathf.Clamp but it started wiggling when the borders reached.
I need smooth movements but Clamp doesnt work fine and my camera always cross the borders a little bit with floating position value. Any ideas ?
This is my Code but I think , you guys needn’t it:
Clamp :
transform.position =
new Vector3(
Mathf.Clamp(transform.position.x, cameraLimits.leftLimit, cameraLimits.rightLimit),
transform.position.y,
Mathf.Clamp(transform.position.z, cameraLimits.downLimit, cameraLimits.upLimit));

Translation Camera:

public Vector3 GetTranslation()
{
float moveX = 0.0f;
float moveZ = 0.0f;
float moveY = 0.0f;

    float moveSpeed = cameraMoveSpeed * Time.deltaTime;

    if (Input.mousePosition.x < mouseScrollLimits.leftLimit)
    {
       // Debug.Log("Left");
        moveX = -moveSpeed;
    }
    else if (Input.mousePosition.x > Screen.width - mouseScrollLimits.rightLimit)
    {
       // Debug.Log("Right");
        moveX = moveSpeed;
    }
    else if (Input.mousePosition.y > Screen.height - mouseScrollLimits.upLimit)
    {
       // Debug.Log("up");

        moveZ = moveSpeed * Mathf.Cos(transform.rotation.eulerAngles.x * (Mathf.PI / 180));
        moveY = moveSpeed * Mathf.Sin(transform.rotation.eulerAngles.x * (Mathf.PI / 180));

    }
    else if (Input.mousePosition.y < mouseScrollLimits.downLimit)
    {
       // Debug.Log("down");
        moveZ =- moveSpeed * Mathf.Cos(transform.rotation.eulerAngles.x * (Mathf.PI / 180));
        moveY =- moveSpeed * Mathf.Sin(transform.rotation.eulerAngles.x * (Mathf.PI / 180));

    }
    return new Vector3(moveX, moveY, moveZ);
}

Mathf.Clamp(transform.position.x …

This implies you assign the position then reassign it with the clamped value. If that’s the case, the solution is to not assign it twice.

Vector3 pos = GetTranslation();
transform.position = new Vector3( Mathf.Clamp(pos.x + transform.position.x, cameraLimits.leftLimit, cameraLimits.rightLimit), pos.y + transform.position.y, Mathf.Clamp(pos.z + transform.position.z, cameraLimits.downLimit, cameraLimits.upLimit));
