|
An ExtensionDtype to hold a single size & kind of integer dtype.
|
|
These specific implementations are subclasses of the non-public
|
IntegerDtype. For example, we have Int8Dtype to represent signed int 8s.
|
|
The attributes name & type are set when these subclasses are created.
|

|
Safely cast the values to the given dtype.
|
|
"safe" in this context means the casting is lossless. e.g. if 'values'
|
has a floating dtype, each value must be an integer.

|
Array of integer (optional missing) values.
|
|
Uses :attr:`pandas.NA` as the missing value.
|
|
.. warning::
|
|
IntegerArray is currently experimental, and its API or internal
|
implementation may change without warning.
|
|
We represent an IntegerArray with 2 numpy arrays:
|
|
- data: contains a numpy integer array of the appropriate dtype
|
- mask: a boolean array holding a mask on the data, True is missing
|
|
To construct an IntegerArray from generic array-like input, use
|
:func:`pandas.array` with one of the integer dtypes (see examples).
|
|
See :ref:`integer_na` for more.
|
|
Parameters
|
----------
|
values : numpy.ndarray
|
A 1-d integer-dtype array.
|
mask : numpy.ndarray
|
A 1-d boolean-dtype array indicating missing values.
|
copy : bool, default False
|
Whether to copy the `values` and `mask`.

--------
|
Create an IntegerArray with :func:`pandas.array`.
|
|
>>> int_array = pd.array([1, None, 3], dtype=pd.Int32Dtype())
|
>>> int_array
|
<IntegerArray>
|
[1, <NA>, 3]
|
Length: 3, dtype: Int32
|
|
String aliases for the dtypes are also available. They are capitalized.
|
|
>>> pd.array([1, None, 3], dtype='Int32')
|
<IntegerArray>
|
[1, <NA>, 3]
|
Length: 3, dtype: Int32
|
|
>>> pd.array([1, None, 3], dtype='UInt16')
|
<IntegerArray>
|
[1, <NA>, 3]
|
Length: 3, dtype: UInt16
