Question about 'rotation' units

[davechurchill]

I am curious if you know exactly what units the 'rotation' data structure holds. For example, the z-axis 'rotation' appears to be:

• 0 when facing east
• 1 when facing west
• -0.7 when facing north
• +0.7 when facing south

I get the 0 / 1 for the east/west, buy why 0.7 for north/south? It's very close to sqrt(2)/2 but I can't decipher what's going on

Rotations should just be quaternions. Rotations used to be simply euler angles but got changed to quaternions some time in 2018/2019
