In cryptography, >>> and <<< are bit rotations of a register; if you have an integer number of divisions of the circle, that might work. I'd use something like \circlearrowright: http://www.w3.org/TR/2008/WD-xml-entity-names-20080721/glyphs/021/U021BB.png On Fri, Feb 12, 2010 at 8:37 AM, Dan Asimov <dasimov@earthlink.net> wrote:

But that's not quite what I'm looking for; I want to bypass radians entirely.

Alas I don't recall the symbology, but I liked his adoption of "turn" for the unit of full rotation (previously I've resorted to "cycle", from pre-metricked-up audio)...

(Of course this is 2pi radians, but for certain purposes it would be more convenient to refer solely to the number of rotations, not radians.)
If there is no standard symbol for this, I propose a circle with a dot in the center. Comments?
