```python
tensorplay.functional.logaddexp2(input, other, *, out=None) → Tensor
```

Logarithm of the sum of exponentiations of the inputs in base-2.

Calculates pointwise $\log_2\left(2^x + 2^y\right)$. See
tensorplay.logaddexp() for more details.

Parameters:

- input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

- other ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the second input tensor

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.
