nextafter
= <xarray.ufuncs._UFuncDispatcher object>¶ xarray specific variant of numpy.nextafter. Handles xarray.Dataset, xarray.DataArray, xarray.Variable, numpy.ndarray and dask.array.Array objects with automatic dispatching.
Documentation from numpy:
nextafter(x1, x2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])
Return the next floating-point value after x1 towards x2, element-wise.
- Parameters
x1 (array_like) – Values to find the next representable value of.
x2 (array_like) – The direction where to look for the next representable value of x1.
out (ndarray, None, or tuple of ndarray and None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
**kwargs – For other keyword-only arguments, see the ufunc docs.
- Returns
out – The next representable values of x1 in the direction of x2. This is a scalar if both x1 and x2 are scalars.
- Return type
ndarray or scalar
Examples
>>> eps = np.finfo(np.float64).eps >>> np.nextafter(1, 2) == eps + 1 True >>> np.nextafter([1, 2], [2, 1]) == [eps + 1, 2 - eps] array([ True, True])
