Range -180 .. 180 transformed into 0 .. 360 smells like angles. If this is the case, simply adding 180 will invert your phase, so you'd probably better do something like: 
   # Add a complete round angle, i.e. 360 degrees
   $angle += 360 if ($angle < 0);

unless you actually want to invert phase. Or unless they're not angles :)

Don't fool yourself.
