# 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

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.
