# DML_ELEMENT_WISE_ROUND_OPERATOR_DESC structure (directml.h)

Rounds each element of *InputTensor* to an integer value, placing the result into the corresponding element of *OutputTensor*.

This operator supports in-place execution, meaning that *OutputTensor* is permitted to alias *InputTensor* during binding.

## Syntax

```
struct DML_ELEMENT_WISE_ROUND_OPERATOR_DESC {
const DML_TENSOR_DESC *InputTensor;
const DML_TENSOR_DESC *OutputTensor;
DML_ROUNDING_MODE RoundingMode;
};
```

## Members

`InputTensor`

Type: **const DML_TENSOR_DESC***

The input tensor to read from.

`OutputTensor`

Type: **const DML_TENSOR_DESC***

The output tensor to write the results to.

`RoundingMode`

Type: **DML_ROUNDING_MODE**

A DML_ROUNDING_MODE determining the direction to round towards.

- If
**DML_ROUNDING_MODE_HALVES_TO_NEAREST_EVEN**: values are rounded to the nearest integer, with halfway values (for example, 0.5) being rounded toward the nearest even integer. - If
**DML_ROUNDING_MODE_TOWARD_ZERO**: values are rounded toward zero. This effectively truncates the fractional part. - If
**DML_ROUNDING_MODE_TOWARD_INFINITY**: values are rounded to the nearest integer, with halfway values (for example, 0.5) being rounded away from zero (toward positive or negative infinity, depending on the sign of the value).

## Availability

This operator was introduced in `DML_FEATURE_LEVEL_2_1`

.

## Tensor constraints

*InputTensor* and *OutputTensor* must have the same *DataType*, *DimensionCount*, and *Sizes*.
