(let ((x (random 1d-3)))
(values (prin1-to-string x) (format nil "~E" x)))
will produce different significant digits. I think the problem is in ~E
which calls lisp::scale-exponent to scale the number between 0.1 and 1. I
think we could just call flonum-to-digits which will give us the digits
and the exponent. We can massage that into the desired digits and
exponent as in scale-exponent, but we won't have the round-off problem.
Maybe.
