dpnp.signbit

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

Returns element-wise True where signbit is set (less than zero).

For full documentation refer to numpy.signbit.

Returns:: out – A boolean array with indication of the sign of each element of x.
Return type:: dpnp.ndarray

Limitations

Parameters x is only supported as either dpnp.ndarray or dpctl.tensor.usm_ndarray. 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 array data types are limited by supported real-valued data types.

Examples

>>> import dpnp as np
>>> np.signbit(np.array([-1.2]))
array([True])

>>> np.signbit(np.array([1, -2.3, 2.1]))
array([False,  True, False])
