misc/44767: floating point support broken in QEMU
>Synopsis: floating point support broken in QEMU

>Originator: Jukka Ruohonen
>Release: NetBSD 5.1_STABLE
This was caught by automated test runs . In NetBSD x86_64 guest under QEMU:
floor(16.999989) = 17.
Presumably such a fundamental error either causes or implies other serious
floating point bugs in QEMU. Remarks:
(a) This does not fail on i386 NetBSD QEMU guest.
(b) This does not fail on "native" i386 or amd64 NetBSD.
Given (b), I am inclined to think that this is a bug in QEMU, but I don't
know it well enough to draw an actual conclusion.
