Not the topic of this thread, but I really think that "NaN in RR" should
return False. RR represents the real numbers and NaN is *not a number*.
Note that Sage usually defines "x in P" as "P(x) == x" which would
actually give False for NaN since NaN != NaN.
Whether Infinity should be in RR is a more borderline question, but I
don't mind that RR(1)/RR(0) gives Infinity.
