Any reason why my !RADEG values appear to be different than the ones
posted above? When I run the same commands I get different results:

IDL> map_set, /continents, /grid
IDL> print,map_proj_forward([-90,90],[-45,45])*!RADEG
-90.000001 -45.000001
90.000001 45.000001

Not a huge difference but it seems to me like the conversion factor
should be the same, right?
