dpnp.floor_divide

dpnp.floor_divide(x1, x2, out=None, where=True, order='K', dtype=None, subok=True, **kwargs)

Calculates the ratio for each element x1_i of the input array x1 with the respective element x2_i of the input array x2 to the greatest integer-value number that is not greater than the division result.

For full documentation refer to numpy.floor_divide.

Parameters:

  • x1 ({dpnp.ndarray, usm_ndarray, scalar}) -- First input array, expected to have numeric data type. Both inputs x1 and x2 can not be scalars at the same time.

  • x2 ({dpnp.ndarray, usm_ndarray, scalar}) -- Second input array, also expected to have numeric data type. Both inputs x1 and x2 can not be scalars at the same time. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

  • out ({None, dpnp.ndarray, usm_ndarray}, optional) -- Output array to populate. Array must have the correct shape and the expected data type. Default: None.

  • order ({"C", "F", "A", "K"}, optional) -- Memory layout of the newly output array, if parameter out is None. Default: "K".

Returns:

out -- An array containing the result of element-wise floor of division. The data type of the returned array is determined by the Type Promotion Rules.

Return type:

dpnp.ndarray

Limitations

Parameters where and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise NotImplementedError exception will be raised.

Examples

>>> import dpnp as np
>>> np.floor_divide(np.array([1, -1, -2, -9]), -2)
array([-1,  0,  1,  4])

>>> np.floor_divide(np.array([1., 2., 3., 4.]), 2.5)
array([ 0.,  0.,  1.,  1.])

The // operator can be used as a shorthand for floor_divide on dpnp.ndarray.

>>> x1 = np.array([1., 2., 3., 4.])
>>> x1 // 2.5
array([0., 0., 1., 1.])
