How to rotate only Y Axis??

Question

I have a joystick and i want my character only rotate in Y depending the joystick direction. But i can´t make it.

 float p = Mathf.Atan2(joystick.Vertical, joystick.Horizontal) * Mathf.Rad2Deg;

I got the pending but only gives me values between -90 to 90. And i need my character to rotate between 0 to 270.
My character moves:
up = 0
right = 90
down = 180
left = 270

I hope you can help a little with this. Thanks a lot

                 float angle= 0;
                 if (joystick.Horizontal > 0)
                 {
                     angle= 90;
                     angle-= 90 * joystick.Vertical;
                 }
                 else
                 {
                     angle= -90;
                     angle+= 90 * joystick.Vertical;
                 }
     
                 Vector3 v = new Vector3(0, angle, 0);
                 transform.localRotation = Quaternion.Euler(v);

Finally i got it. A friend help me to do it.

First we declare the angle to 0 and we check if our joystick is moving horizontal.

When it is bigger than 0 ( it means that the joystick is moving to the right ) so the angle to move my object to right is 90. So i put it 90 then that angle i subtract 90 * joystick.Vertical
So according to my angle that i expect to move in that way that is between 90 to 180 and 0. So only we need to multiply to the value of the vertical that it is between 1 to -1. So if it is positive, it means that the stick is moving up. And with the other is the same way.

Finally i get the angle to a vector3. That i make a Quaternion.Euler to make the rotation and i assign it to the rotation to my object.
