Round - version 11
==================

This page documents version **11** of operator **Round**. See :doc:`Round` for the latest version (since version 22).

- **Domain**: ``ai.onnx``
- **Since version**: 11

Round takes one input Tensor and rounds the values, element-wise, meaning
it finds the nearest integer for each value.
In case of halves, the rule is to round them to the nearest even integer.
If input x is integral, +0, -0, NaN,  or infinite, x itself is returned.
The output tensor has the same shape and type as the input.

Examples:

.. code-block::

    round([0.9]) = [1.0]
    round([2.5]) = [2.0]
    round([2.3]) = [2.0]
    round([1.5]) = [2.0]
    round([-4.5]) = [-4.0]


**Inputs**

- **X** (*T*): Input tensor

**Outputs**

- **Y** (*T*): Output tensor

**Type Constraints**

- **T**: Constrain input and output types to float tensors.
  Allowed types: tensor(double), tensor(float), tensor(float16).
