# tensorplay.functional.frac

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

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

Computes the fractional portion of each element in input.

$$\text{out}_{i} = \text{input}_{i} - \left\lfloor |\text{input}_{i}| \right\rfloor * \operatorname{sgn}(\text{input}_{i})$$

Example:

```
>>> tensorplay.frac(tensorplay.tensor([1, 2.5, -3.2]))
tensor([ 0.0000,  0.5000, -0.2000])
```
