dpnp.signbit

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

Computes an indication of whether the sign bit of each element x_i of input array x is set.

For full documentation refer to numpy.signbit.

Parameters:

  • x ({dpnp.ndarray, usm_ndarray}) -- Input array, expected to have numeric 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 ({"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 signbit results. The returned array must have a data type of bool.

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.signbit(np.array([-1.2]))
array([True])

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