Issue regarding usage of np.bitwise_and on pandas Series

[Manprit Singh]

I have two Series

sa = pd.Series([1, 0, 1], index=list("ABC"))
sb = pd.Series([0, 0, 1], index=list("ABC"))

np.bitwise_and(sa, sb) gives the right answer as below:

A 0

B 0

C 1

dtype: int 64

When when using unaligned series as below:

sa = pd.Series([1, 0, 1], index=list("ABC"))
sb = pd.Series([0, 0, 1], index=list("ACB"))

np.bitwise_and(sa, sb), gives the result in terms of boolean values as below :

A False

B False

C False

dtype : bool

How can a bitwise_ and, can give the result in boolean when series are not alligned .
