Pandas version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
s = pd.Series([1, 2, None], dtype="Int32")
s.apply(lambda x: print(x))
s.map(lambda x: print(x))
# print 1.0 2.0 nan instead of 1 2 <NA>
Issue Description
s
has dtype Int32Dtype
which can encode nullable integers
However, when we use .apply(f)
or .map(f)
, the element passed to f
becomes float, and pd.NA
becomes np.nan
Expected Behavior
f
should receive unconverted value, as if we are doing f(s.iloc[0])
, f(s.iloc[1])
, ...
Installed Versions
