Chris already stated that the case gives the answer he expects in
several other DBs, so I don't seem much need for further compatibility
checking on the "don't round off prematurely" angle. However, it would
be interesting to know what Oracle etc do with NaN and Infinity,
assuming they even support such numbers.
Currently what our code does for the format-with-EEEE case is to output
"#" in all digit positions. It would be plausible for that to happen
in the non-EEEE cases too, but whether that's actually what happens in
other systems is something I don't know.
