## LessOrEqual - 16

### Version

- **name**: [LessOrEqual (GitHub)](https://github.com/onnx/onnx/blob/main/docs/Operators.md#LessOrEqual)
- **domain**: `main`
- **since_version**: `16`
- **function**: `True`
- **support_level**: `SupportType.COMMON`
- **shape inference**: `True`

This version of the operator has been available
**since version 16**.

### Summary

Returns the tensor resulted from performing the `less_equal` logical operation
elementwise on the input tensors `A` and `B` (with Numpy-style broadcasting support).

This operator supports **multidirectional (i.e., Numpy-style) broadcasting**; for more details please check [Broadcasting in ONNX](https://github.com/onnx/onnx/blob/main/docs/Broadcasting.md).

#### Function Body

The function definition for this operator.

```
<
  domain: "",
  opset_import: ["" : 16]
>
LessOrEqual (A, B) => (C)
{
   O1 = Less (A, B)
   O2 = Equal (A, B)
   C = Or (O1, O2)
}
```

### Inputs

- **A** (heterogeneous) - **T**:

  First input operand for the logical operator.
- **B** (heterogeneous) - **T**:

  Second input operand for the logical operator.

### Outputs

- **C** (heterogeneous) - **T1**:

  Result 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 types to all numeric tensors.
* **T1** in ( `tensor(bool)` ):

  Constrain output to boolean tensor.
