We recently changed round, floor, ceiling, and trunc on RR to return
integers; yes, I think the corresponding RDF methods should change as
well.

The fix for #2898 will fix this.

This makes floor and ceil do what I expect for RIF. I believe that #2898 does make RDF work.

I just tried to apply this against 3.2, and it fails. It's just a matter of moving the doctests around, I think.
