#1: prin1 and ~E produce different outputs. ------------------------+--------------------------------------------------- Reporter: anonymous | Owner: somebody Type: defect | Status: new Priority: minor | Milestone: Component: component1 | Version: Keywords: printing | ------------------------+--------------------------------------------------- (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. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/1> cmucl <http://common-lisp.net/project/cmucl> cmucl
