Angles

a
The Player's yaw (facing) is a float (from $$-180.0$$ to $$180.0$$)

An angle is an integer (from $$0$$ to$$2^16$$)

A single angle spans approximately 0.0055°

Minecraft uses angles for movement calculations, which means the Player's yaw has to be converted before being used.

This conversion induces some imprecision.
