Ceiling

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

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

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.

C++ Interface

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

Elementwise ceiling operation.

Public Functions

Ceiling(const std::shared_ptr<Node> &arg)

Constructs a ceiling operation.

Parameters
  • arg: Node that produces the input tensor.
