In read(vrjoystick), what value does "povs" take?

Hi guys.

So I've been trying to read the status of my joystick connected to pc by

[axes, buttons, povs] = read(vrjoystick)

but I was wondering about the values that "povs" take. (-1, 0, and 1, I am guessing??)

In the command window I have written:

   povs

to see the actual value of povs, but Matlab is too busy to show anything before bearable amount of waiting.

Anyone having done similar stuff? I need help :(

At absolute minimum, the possible values are -1 (not available), 0, 90, 180, and 270.

I find evidence such as at https://forums.tigsource.com/index.php?topic=36675.0 that the 45 degree angles are also possible.
