(l-onnx-op-abs-13)=

## Abs - 13

### Version

- **name**: [Abs (GitHub)](https://github.com/onnx/onnx/blob/main/docs/Operators.md#Abs)
- **domain**: `main`
- **since_version**: `13`
- **function**: `False`
- **support_level**: `SupportType.COMMON`
- **shape inference**: `True`

This version of the operator has been available
**since version 13**.

### Summary

Absolute takes one input data (Tensor<T>) and produces one output data
(Tensor<T>) where absolute value, y = abs(x), is applied to
the tensor elementwise.

### Inputs

- **X** (heterogeneous) - **T**:

  Input tensor

### Outputs

- **Y** (heterogeneous) - **T**:

  Output tensor

### Type Constraints

* **T** in ( `tensor(bfloat16)`, `tensor(double)`, `tensor(float)`, `tensor(float16)`, `tensor(int16)`, `tensor(int32)`, `tensor(int64)`, `tensor(int8)`, `tensor(uint16)`, `tensor(uint32)`, `tensor(uint64)`, `tensor(uint8)` ):

  Constrain input and output types to all numeric tensors.
