Does rotate_extrude angle property allow for values that don't divide 360 evenly?

I've not tried the 2016 version yet, but I was wondering if the angle is
capable of being a value that doesn't evenly divide 360 and yet have the
sweep radial extents that have a radius that is that of the circumscribed
circle generated by the 2D object?

you can state any positive or negative decimal value as angle. Angles larger
than 360 or smaller than -360 are procrusted to 360;

Imho, angle must be whole number, therefore if You want seamless rotation
number of degrees are  limited to 1,2,3,4, 6, 9. 10, 12, 18, 20, 36, 60,
90, 120 and 180.

Why not? Do you have any example where rotate_extrude doesn't work with
angle of, say, 360/7 degrees? Have you tried it?

BTW, 360 has many more divisors besides your list.

Yes but what does that have to do with rotate_extrude()? That should work
with any angle, and seems to when I try it.

If my real world grasshopper leg exoskeleton hinge NEEDS to use 314.15925

Angles measured in degrees are internally converted to radians before they
are used. Which means that factors of 360 will be converted to floating
point approximations of trancendental numbers. Just FYI.

Sorry that I did not consider Grasshoper Legs. I was only thinking of
uniform rotate extrude.
I guarantee You that my Wind turbines would have no legs. Would like to see
that particular
application of RotateExtrude, without any grass or weeds....

How about a generic polyline extrusion which can have any angle between
segments?

So, am I to assume that if I wanted an sweep angle that is not evenly
divisible by 360, I would have to roll my own solution?  Too bad as that
will reduce the preview speed.
