No, they're correct as they stand. These examples intentionally use negative numbers to make the point that the rounding is towards or away from plus-infinity, not towards or away from zero. If we had room for more than one example, I'd be inclined to make these cases be secondary examples rather than the only one. There's some work afoot to restructure this chapter's function tables in a way that would make that a bit less painful vertical-space-wise, so maybe it'll get done soon. regards, tom lane
