dpnp.floor

dpnp.floor(x, out=None, where=True, order='K', dtype=None, subok=True, **kwargs)

Returns the floor for each element \(x_i\) for input array x.

The floor of \(x_i\) is the largest integer n, such that n <= x_i.

For full documentation refer to numpy.floor.

Parameters:

  • x ({dpnp.ndarray, usm_ndarray}) -- Input array, expected to have a boolean or real-valued data type.

  • 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 ({None, "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 element-wise floor.

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.

See also

dpnp.ceil

Compute the ceiling of the input, element-wise.

dpnp.trunc

Return the truncated value of the input, element-wise.

dpnp.rint

Round elements of the array to the nearest integer.

dpnp.fix

Round to nearest integer towards zero, element-wise.

Notes

Some spreadsheet programs calculate the "floor-towards-zero", where floor(-2.5) == -2. DPNP instead uses the definition of dpnp.floor where floor(-2.5) == -3. The "floor-towards-zero" function is called dpnp.fix in DPNP.

Examples

>>> import dpnp as np
>>> a = np.array([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0])
>>> np.floor(a)
array([-2.0, -2.0, -1.0, 0.0, 1.0, 1.0, 2.0])
