# What is the use of the "round" function in Python?

The `**round**`

function in Python is used to round a floating-point number to a specified number of decimal places. The rounded value is returned as a float. The basic syntax for the `**round**`

function is:

```
round(number, ndigits)
```

where `**number**`

is the floating-point number to be rounded, and `**ndigits**`

is the number of decimal places to round to. If `**ndigits**`

is not specified, the number is rounded to the nearest whole number. The `**round**`

function uses "round half to even" or "bankers' rounding" by default, which rounds to the nearest even number if the fractional part is exactly 0.5.
