[Python-Dev] Math.sqrt(-1) -- nan or ValueError?

[Hasan Diwan]

I'm trying to fix a failing unit test in revision 57974. The test in
question claims that math.sqrt(-1) should raise ValueError; the code itself
gives "nan" as a result for that expression. I can modify the test and
therefore have it pass, but I'm not sure if an exception would be more
appropriate. I'd be happy for some direction here. Many thanks!
