ondition is broadcast over the input. At locations where the
    condition is True, the `out` array will be set to the ufunc result.
    Elsewhere, the `out` array will retain its original value.
    Note that if an uninitialized `out` array is created via the default
    ``out=None``, locations within it where the condition is False will
    remain uninitialized.
**kwargs
    For other keyword-only arguments, see the
    :ref:`ufunc docs <ufuncs.kwargs>`.

Returns
-------
y : ndarray
    The element-wise remainder of the quotient ``floor_divide(x1, x2)``.
    This is a scalar if both `x1` and `x2` are scalars.

See Also
--------
floor_divide : Equivalent of Python ``//`` operator.
divmod : Simultaneous floor division and remainder.
fmod : Equivalent of the MATLAB ``rem`` function.
divide, floor

Notes
-----
Returns 0 when `x2` is 0 and both `x1` and `x2` are (arrays of)
integers.
``mod`` is an alias of ``remainder``.

Examples
--------
>>> import numpy as np
>>> np.remainder([4, 7], [2, 3])
array([0, 1])
>>> np.remainder(np.arange(7), 5)
array([0, 1, 2, 3, 4, 0, 1])

The ``%`` operator can be used as a shorthand for ``np.remainder`` on
ndarrays.

>>> x1 = np.arange(7)
>>> x1 % 5
array([0, 1, 2, 3, 4, 0, 1])
