round:
    description: |
        Returns half to even of a tensor element-wise.

        .. math::

            out_i \approx input_i

        Args:
            input (Tensor): The input tensor.

        Returns:
            Tensor, has the same shape and type as the `input`.

        Raises:
            TypeError: If `input` is not a Tensor.

        Supported Platforms:
            ``Ascend`` ``GPU`` ``CPU``

        Examples:
            >>> import mindspore
            >>> import numpy as np
            >>> from mindspore import Tensor, ops
            >>> input = Tensor(np.array([0.8, 1.5, 2.3, 2.5, -4.5]), mindspore.float32)
            >>> output = ops.round(input)
            >>> print(output)
            [ 1.  2.  2.  2. -4.]
