# tensorplay.functional.ceil

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.ceil.html

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

Returns a new tensor with the ceil of the elements of input,
the smallest integer greater than or equal to each element.

For integer inputs, follows the array-api convention of returning a
copy of the input tensor.

$$\text{out}_{i} = \left\lceil \text{input}_{i} \right\rceil$$

Parameters:

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

Keyword Arguments:

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

Example:

```
>>> a = tensorplay.randn(4)
>>> a
tensor([-0.6341, -1.4208, -1.0900,  0.5826])
>>> tensorplay.ceil(a)
tensor([-0., -1., -1.,  1.])
```
