Comment(by dustymugs):

 If you look at the docs for ST_Slope, ST_Azimuth and ST_Hillshade in 2.0,
 there was absolutely no units described.  So, when I was going through the
 code to make sure the results matched that of ArcGIS (I assume most folks
 are going to compare to that application), I noticed that ArcGIS uses
 degrees by default.  And since our functions where not documented, I went
 with degrees...

 Personally, I like degrees...
