the result of this operation, should be between -180 and 180, right?
To put that between 0 and 360, I would use something like
[moses 0]
|            |
[+360]   |
|            /
[f ]

This would be kind of tricky in terms of math, if you want for the
intermediate joystick values (not just the direction) to control the
sound distribution.  You likely want to have the sum of squares of
your output signals to remain constant (constant total intensity)
regardless of joystick position.
