[racket] order-of-magnitude (was ~r: formatting 0.0 with 'exponential and #:precision)

I have speeded up the procedure a little bit by avoiding to recompute the
inverse of the logarithm of the base each time the procedure is called.
Please let me know whether or not you want the new version. In that case
I'll send you the new version.
