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.

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

const std::string &description() const

Get the string name for the type of the node, such as Add or Multiply. The class name, must not contain spaces as it is used for codegen.

Return

A const reference to the node’s type name

Ceiling()

Constructs a ceiling operation.

Ceiling(const Output<Node> &arg)

Constructs a ceiling operation.

Parameters
  • arg: Node that produces the input tensor.
