Convert from point to 1/8 circle

Unit Definition (point)
The point is a unit of angle measure equal to 1/32 of a circle. Compasses are read by suspending the compass needle over a compass card traditionally inscribed with a 32-point star. Each point of the star represents a named direction; for example, the first five points from north towards east are labeled North, North by East, North Northeast, Northeast by North, and Northeast. The difference between two directions can be expressed as a certain number of these compass points. One point equals 11°15' of arc or pi/16 radians.
