In Python, the **`round()` function** rounds a number off to the specified decimal place. The value returned by the function is a floating point.

# Syntax
```python
round(number, decimals)
```

- **`number`:** The actual number which needs to be rounded; it is a compulsory argument.

- **`decimals`:** The number of decimal places to be rounded to; it is an optional argument.

By default, the number is rounded to `0` decimal places unless specified otherwise in the `decimals` argument.

num = 5.4739

# The default call
print(round(num))

# Specified decimal place
print(round(num, 2))

# More decimal places than the number contains
print(round(num, 8)) # Original number returned
