# tensorplay.functional.reciprocal

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

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

Returns a new tensor with the reciprocal of the elements of input

$$\text{out}_{i} = \frac{1}{\text{input}_{i}}$$

> **Note**
>
> Unlike NumPy’s reciprocal, tensorplay.reciprocal supports integral inputs. Integral inputs to reciprocal are automatically promoted to the default scalar type.

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([-0.4595, -2.1219, -1.4314,  0.7298])
>>> tensorplay.reciprocal(a)
tensor([-2.1763, -0.4713, -0.6986,  1.3702])
```
