`round` function rounds a number to a given precision in decimal digits.

Values are rounded to the closest multiple of `10 ** (precision)`. For example, for `precision=1` value will be rounded to multiple of 0.1 (`round(0.63, 1)` returns 0.6). If two multiples are equally close, rounding is done toward the even choice:

Sometimes rounding of floats can be a little bit surprising:

This is because most decimal fractions [can't be represented exactly as a float](https://docs.python.org/3.7/tutorial/floatingpoint.html):
```
+```python
>>> format(2.85, '.64f')
'2.8500000000000000888178419700125232338905334472656250000000000000'

If you want to round half up you can use `decimal.Decimal`:
```
+```python
>>> from decimal import Decimal, ROUND_HALF_UP
>>> Decimal(1.5).quantize(0, ROUND_HALF_UP)
Decimal('2')
