Ceiling  // Elementwise ceiling operation


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.


Name Element Type Shape
arg Any Any


Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \lceil \mathtt{arg}_{i_0, \ldots, i_{n-1}}\rceil\]


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.

C++ Interface

class Ceiling : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise ceiling operation.

Public Functions

const NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.


Constructs a ceiling operation.

Ceiling(const Output<Node> &arg)

Constructs a ceiling operation.

  • arg: Node that produces the input tensor.
