Detect if magnetic encoder passes 360 or 0 and in which direction (roll-over/wraparound direction?) - C

I use a magnetic encoder, which reacts on hand inputs. When turning, it calculates the angle, and that part works perfectly. That means that if I turn the encoder 360 degrees, the angle is reset. (therefore it's 0 again). However, I would like to…
