|
Boolean ``or`` using Kleene logic.
|
|
Values are NA where we have ``NA | NA`` or ``NA | False``.
|
``NA | True`` is considered True.
|
|
Parameters
|
----------
|
left, right : ndarray, NA, or bool
|
The values of the array.
|
left_mask, right_mask : ndarray, optional
|
The masks. Only one of these may be None, which implies that
|
the associated `left` or `right` value is a scalar.
|
|
Returns
|
-------
|
result, mask: ndarray[bool]
|
The result of the logical or, and the new mask.

|
Boolean ``xor`` using Kleene logic.
|
|
This is the same as ``or``, with the following adjustments
|
|
* True, True -> False
|
* True, NA -> NA
|
|
Parameters
|
----------
|
left, right : ndarray, NA, or bool
|
The values of the array.
|
left_mask, right_mask : ndarray, optional
|
The masks. Only one of these may be None, which implies that
|
the associated `left` or `right` value is a scalar.
|
|
Returns
|
-------
|
result, mask: ndarray[bool]
|
The result of the logical xor, and the new mask.
