Functions

func DistanceAbsolute

func DistanceAbsolute(out, to, from []byte)

DistanceAbsolute computes the distance moving either clockwise or anticlockwise on the circle. to, from, and out must be the same length or DistanceAbsolute will panic

dist = abs(to - from) = abs(from - to)

func DistanceForward

func DistanceForward(out, to, from []byte)

Distance computes the distance moving clockwise around the circle, starting at a, and going to b. to, from, and out must be the same length or DistanceForward will panic

dist = (to - from) % m where m is the 2^(len(out)*8)a
