.. ceiling.rst: ####### Ceiling ####### .. code-block:: cpp Ceiling // Elementwise ceiling operation Description =========== Produces a single output tensor of the same element type and shape as ``arg,`` where the value at each coordinate of ``output`` is the ceiling of the value at each ``arg`` coordinate. Inputs ------ +-----------------+-------------------------+--------------------------------+ | Name | Element Type | Shape | +=================+=========================+================================+ | ``arg`` | Any | Any | +-----------------+-------------------------+--------------------------------+ Outputs ------- +-----------------+-------------------------+--------------------------------+ | Name | Element Type | Shape | +=================+=========================+================================+ | ``output`` | Same as ``arg`` | Same as ``arg`` | +-----------------+-------------------------+--------------------------------+ Mathematical Definition ======================= .. math:: \mathtt{output}_{i_0, \ldots, i_{n-1}} = \lceil \mathtt{arg}_{i_0, \ldots, i_{n-1}}\rceil Backprop ======== Not defined by nGraph. The backprop would be zero for non-integer input and undefined for integer input; a zero backprop would have no effect on the backprop to ``arg``, so there is no need for ``Ceiling`` to define a backprop.
