Signature de la fonction divmod
Description
divmod.__doc__
divmod(x1, x2[, out1, out2], / [, out=(None, None)], *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])
Return element-wise quotient and remainder simultaneously.
.. versionadded:: 1.13.0
``np.divmod(x, y)`` is equivalent to ``(x // y, x % y)``, but faster
because it avoids redundant work. It is used to implement the Python
built-in function ``divmod`` on NumPy arrays.
Parameters
----------
x1 : array_like
Dividend array.
x2 : array_like
Divisor array.
If ``x1.shape != x2.shape``, they must be broadcastable to a common
shape (which becomes the shape of the output).
out : ndarray, None, or tuple of ndarray and None, optional
A location into which the result is stored. If provided, it must have
a shape that the inputs broadcast to. If not provided or None,
a freshly-allocated array is returned. A tuple (possible only as a
keyword argument) must have length equal to the number of outputs.
where : array_like, optional
This condition 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
-------
out1 : ndarray
Element-wise quotient resulting from floor division.
This is a scalar if both `x1` and `x2` are scalars.
out2 : ndarray
Element-wise remainder from floor division.
This is a scalar if both `x1` and `x2` are scalars.
See Also
--------
floor_divide : Equivalent to Python's ``//`` operator.
remainder : Equivalent to Python's ``%`` operator.
modf : Equivalent to ``divmod(x, 1)`` for positive ``x`` with the return
values switched.
Examples
--------
>>> np.divmod(np.arange(5), 3)
(array([0, 0, 0, 1, 1]), array([0, 1, 2, 0, 1]))
The `divmod` function can be used as a shorthand for ``np.divmod`` on
ndarrays.
>>> x = np.arange(5)
>>> divmod(x, 3)
(array([0, 0, 0, 1, 1]), array([0, 1, 2, 0, 1]))
