    What is the radius of a circular buffer?

      radius = circumference / (2*Pi), of course!

      If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

          In Bits I think it is something like this: r= BufferLength * BitPerEntry / 2 / π

            circumference = 2*Pi*radius Infinite Loop: see Infinite Loop :)

              circumference/Pie*R*Round -r (recursive)

                The same as the radius of a circular argument.

                      Warning: Be careful doing live experiments to calculate the answer, to many tests running at the same time greatly increases risk of a buffer low stampede.

                      Sin tack the any key okay

                        This is how buffer overruns occur. If the radius is too little, the circumference won't have enough room for all the buffer elements.

                          r = c / (2 * π)
