dpnp.sign

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

Returns an element-wise indication of the sign of a number.

For full documentation refer to numpy.sign.

Returns:: out – The 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 DPNP Data types. However, if the input array data type is complex, the function will be executed sequentially on CPU.

Examples

>>> import dpnp as np
>>> np.sign(np.array([-5., 4.5]))
array([-1.0, 1.0])
>>> np.sign(np.array(0))
array(0)
>>> np.sign(np.array(5-2j))
array([1+0j])
