Unity 2D float inside a vector has decimal places

Sorry for the weird/unsuggesting title but here’s the deal:

When I create a movement vector and then apply it to my character’s rb2d, the number isn’t round.

    float move = 0.8;
    
    Vector3 targetVelocity = new Vector2(move * 10f, m_Rigidbody2D.velocity.y);
    
    m_Rigidbody2D.velocity = Vector3.SmoothDamp(m_Rigidbody2D.velocity, targetVelocity, ref 
    m_Velocity, m_MovementSmoothing);
    
    Debug.Log(m_Rigidbody2D.velocity.x);//8.066598

I would like the number in the Debug.Log to come out as 8, but without having to use Mathf.Round.
What part of my code makes the velocity.x not be a round number?

A float will never be a round number, that’s the nature of floats, if you want it to be a whole number cast it to an integer, integers are whole numbers.

Debug.Log((int)m_Rigidbody2D.velocity.x);

You can also format numbers as strings to show as many decimal places you want.
