## IsInf - 20

### Version

- **name**: [IsInf (GitHub)](https://github.com/onnx/onnx/blob/main/docs/Operators.md#IsInf)
- **domain**: `main`
- **since_version**: `20`
- **function**: `False`
- **support_level**: `SupportType.COMMON`
- **shape inference**: `True`

This version of the operator has been available
**since version 20**.

### Summary

Map infinity to true and other values to false.

### Attributes

* **detect_negative - INT** (default is `'1'`):

  (Optional) Whether map negative infinity to true. Default to 1 so that negative infinity induces true. Set this attribute to 0 if negative infinity should be mapped to false.

* **detect_positive - INT** (default is `'1'`):

  (Optional) Whether map positive infinity to true. Default to 1 so that positive infinity induces true. Set this attribute to 0 if positive infinity should be mapped to false.

### Inputs

- **X** (heterogeneous) - **T1**:

  input

### Outputs

- **Y** (heterogeneous) - **T2**:

  output

### Type Constraints

* **T1** in ( `tensor(bfloat16)`, `tensor(double)`, `tensor(float)`, `tensor(float16)`, `tensor(float8e4m3fn)`, `tensor(float8e4m3fnuz)`, `tensor(float8e5m2)`, `tensor(float8e5m2fnuz)` ):

  Constrain input types to float tensors.
* **T2** in ( `tensor(bool)` ):

  Constrain output types to boolean tensors.
