#5: (sin +pi+) should not be zero --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: Keywords: | --------------------+------------------------------------------------------- Since +pi+ is not the mathematical pi, (sin +pi+) cannot be zero. This is caused by doing a sloppy pi reduction for small args. -- Ticket URL: <http://trac.common-lisp.net/oct/ticket/5> oct <http://common-lisp.net/project/oct> oct
