Cast to a NumPy array or IntegerArray with ‘dtype’.

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. If False, a copy is made only if the old dtype does not match the new dtype.

Returns:

array : ndarray or IntegerArray

NumPy ndarray or IntergerArray with ‘dtype’ for its dtype.

Raises:

TypeError

if incompatible type with an IntegerDtype, equivalent of same_kind casting
