BUG: div by integer 0 returning non-signed infs (and nan issue) #6178
Description
exposed this bug; going to update the tests (and i'll link there that show it)
initially only showed up on py2.6...but it is real
the signs of the inf under integer division are wrong.
for the most part the np.nan are preserved, not sure if this is right or not
In [1]: Series([np.nan,1,-1])/0
Out[1]:
0 inf
1 inf
2 inf
dtype: float64
In [2]: Series([np.nan,1,-1])/0.
Out[2]:
0 NaN
1 inf
2 -inf
dtype: float64
