Especially the behaviour regarding NaN (distinct from NA missing values) is subject to change. We represent a FloatingArray with 2 numpy arrays: - data: contains a numpy float array of the appropriate dtype - mask: a boolean array holding a mask on the data, True is missing To construct an FloatingArray from generic array-like input, use :func:`pandas.array` with one of the float dtypes (see examples). See :ref:`integer_na` for more. Parameters ---------- values : numpy.ndarray A 1-d float-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`. Attributes ---------- None Methods ------- None Returns ------- FloatingArray Examples -------- Create an FloatingArray with :func:`pandas.array`: >>> pd.array([0.1, None, 0.3], dtype=pd.Float32Dtype()) <FloatingArray> [0.1, <NA>, 0.3] Length: 3, dtype: Float32 String aliases for the dtypes are also available. They are capitalized. >>> pd.array([0.1, None, 0.3], dtype="Float32") <FloatingArray> [0.1, <NA>, 0.3] Length: 3, dtype: Float32 g r )r c C s t t| jj� S )N)r/ r rF r8 )r r r r r8 � s zFloatingArray.dtypeFz np.ndarrayr )rR rS r7 c s6 t |tj�r|jjdks td��t� j|||d� d S )N�fzJvalues should be floating numpy array.

Parameters ---------- dtype : str or dtype Typecode or data-type to which the array is cast. copy : bool, default True Whether to copy the data, even if not necessary.

Returns ------- ndarray or ExtensionArray NumPy ndarray, or BooleanArray, IntegerArray or FloatingArray with 'dtype' for its dtype.
