- xarray.ufuncs.signbit(*args, **kwargs)¶
xarray specific variant of numpy.signbit. Handles xarray.Dataset, xarray.DataArray, xarray.Variable, numpy.ndarray and dask.array.Array objects with automatic dispatching.
Documentation from numpy:
signbit(x[, out])
Returns element-wise True where signbit is set (less than zero).
Parameters: x : array_like
The input value(s).
out : ndarray, optional
Array into which the output is placed. Its type is preserved and it must be of the right shape to hold the output. See doc.ufuncs.
Returns: result : ndarray of bool
Output array, or reference to out if that was supplied.
Examples
>>> np.signbit(-1.2) True >>> np.signbit(np.array([1, -2.3, 2.1])) array([False, True, False], dtype=bool)
