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.

arg Any Any

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 NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.


Constructs a floor operation.

Floor(const Output<Node> &arg)

Constructs a floor operation.

  • arg: Node that produces the input tensor.
