# saneround

Python package providing sane round() instead of official insane round().

## Quick start

Install this package using pip:

pip install saneround
```

Import `saneround` package as `sr` and use `sr.round(number: Union[int, float], ndigits: int = 0) -> float`:

```python
>>> import saneround as sr
>>> sr.round(0.4)
0.0
>>> sr.round(0.5)
1.0
>>> sr.round(1.4)
1.0
>>> sr.round(1.5)
2.0
>>> sr.round(-0.4)
0.0
>>> sr.round(-0.5)
-1.0
>>> sr.round(-1.4)
-1.0
>>> sr.round(-1.5)
-2.0
>>> sr.round(1234.567, 2)
1234.57
>>> sr.round(1234.576, -2)
1200.0
```
