## [ 组合替代实现 ]torch.\_foreach_round
### [torch.\_foreach\_round](https://docs.pytorch.org/docs/stable/generated/torch._foreach_round.html#torch._foreach_round)
```python
torch._foreach_round(self)
```

Paddle 无此 API，需要组合实现。

### 转写示例
```python
# PyTorch 写法
torch._foreach_round(tensors)

# Paddle 写法
[paddle.round(x) for x in tensors]
```
