+<dd><p><code>ISHFTC</code> returns a value corresponding to <var>I</var> with the
+rightmost <var>SIZE</var> bits shifted circularly <var>SHIFT</var> places; that
+is, bits shifted out one end are shifted into the opposite end. A value
+of <var>SHIFT</var> greater than zero corresponds to a left shift, a value of
+zero corresponds to no shift, and a value less than zero corresponds to
+a right shift. The absolute value of <var>SHIFT</var> must be less than
+<var>SIZE</var>. If the <var>SIZE</var> argument is omitted, it is taken to be
+equivalent to <code>BIT_SIZE(I)</code>.
