In this case, 1/262144 of a circle as it was on an 18
bit computer,
but today you would probably use 32 bits. There's nothing special
about dividing a circle into 360 parts anyway, 420 would have allowed
2PI are Round!
There are 2Pi radians in a circle, very few in the graphics world use interger degrees for
anything other
than human readable or heman generated I/O. A line is bounded by 2 points or can be
described as a
angle and distance from a relitave point. While Arc's can be specified by a start,
end, and center point,
Curves are almost always specified in radians. Autodesk had an interesting bulge value.
In the graphics world 2 pi are round and can represent an infinate number of angles, and
truely not
square :)
