Round

Versioned name: Round-5

Category: Arithmetic unary operation

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

<layer ... type="Round">
    <data mode="half_to_even"/>
    <input>
        <port id="0">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </input>
    <output>
        <port id="1">
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </output>
</layer>
