Here's how to understand this:

* Compass Bearings: Compass bearings are measured clockwise from North (0 degrees).

* Cardinal Directions: The main directions (North, East, South, West) are at 0, 90, 180, and 270 degrees, respectively.

* Intercardinal Directions: Directions between the cardinal directions (like Northeast, Southeast, Southwest, Northwest) are at 45, 135, 225, and 315 degrees.

Since 22.5 degrees is a little past North (0 degrees) and heading towards Northeast (45 degrees), it falls within the NNE direction.
