Makes sense. But the likelihood of a symbol's being used is inversely proportional to the amount of writing it requires.* So maybe letting that circular arrow evolve naturally, it would become something like an upper semicircle with a short vertical stroke on its left or on its right . . .? Alternatively, a sideways 6 vs. a sideways 9 might work. * * * As for *why* anyone would want such a symbol: In some research I'm doing, for a long time I've been writing fractions of a circle in radians and finally got tired of writing all those pis when only which fraction of a circle -- not its arclength -- is relevant. --Dan ____________________________________________________________________ * This is the *real* reason that more numbers start with 1 than with other digits, pace Benford's Law. ________________________________________________________________________________________ "Outside of a dog, a book is man's best friend.
