dpnp.left_shift

dpnp.left_shift(x1, x2, /, out=None, *, order='K', where=True, dtype=None, subok=True, **kwargs)[source]

Shift the bits of an integer to the left.

For full documentation refer to numpy.left_shift.

Returns:: out – An array containing the element-wise results.
Return type:: dpnp.ndarray

Limitations

Parameters x1 and x2 are supported as either scalar, dpnp.ndarray or dpctl.tensor.usm_ndarray, but both x1 and x2 can not be scalars at the same time. Parameters where, dtype and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise the function will be executed sequentially on CPU. Input data is supported as integer only.

Examples

>>> import dpnp as np
>>> x1 = np.array([5])
>>> x2 = np.array([1, 2, 3])
>>> np.left_shift(x1, x2)
array([10, 20, 40])

The << operator can be used as a shorthand for left_shift on dpnp.ndarray.

>>> x1 << x2
array([10, 20, 40])
