## Round <a name="Round"></a> {#openvino_docs_ops_arithmetic_Round_5}
**Versioned name**: *Round-5*
**Category**: *Arithmetic unary*
**Short description**: *Round* performs element-wise round operation with given tensor.
**Detailed description**: Operation 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 `mode` attribute is `half_to_even` or rounding in such a way that the result heads away from zero if `mode` attribute is `half_away_from_zero`.
Input = [-4.5, -1.9, -1.5, 0.5, 0.9, 1.5, 2.3, 2.5]
round(Input, mode = `half_to_even`) = [-4.0, -2.0, -2.0, 0.0, 1.0, 2.0, 2.0, 2.0]
round(Input, mode = `half_away_from_zero`) = [-5.0, -2.0, -2.0, 1.0, 1.0, 2.0, 2.0, 3.0]
**Attributes**:
* *mode*
* **Description**: If set to `half_to_even` then the rule is to round halves to the nearest even integer, if set to `half_away_from_zero` then rounding in such a way that the result heads away from zero.
* **Range of values**: `half_to_even` or `half_away_from_zero`
* **Type**: string
* **Default value**: `half_to_even`
* **Required**: *no*
**Inputs**
* **1**: A tensor of type *T*. **Required.**
**Outputs**
* **1**: The result of element-wise round operation. A tensor of type *T*.
**Types**
* *T*: any numeric type.
**Example**
