Floor  // Elementwise floor 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 floor 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

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


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

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.

A const reference to the node’s type name


Constructs a floor operation.

Floor(const Output<Node> &arg)

Constructs a floor operation.

  • arg: Node that produces the input tensor.
