# Floor¶

Floor  // Elementwise floor 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 floor 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¶

$\mathtt{output}_{i_0, \ldots, i_{n-1}} = \lfloor \mathtt{arg}_{i_0, \ldots, i_{n-1}}\rfloor$

## 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 Floor to define a backprop.

## C++ Interface¶

class Floor : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise floor operation.

Public Functions

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

Constructs a floor operation.

Parameters
• arg: Node that produces the input tensor.
