56

#### Explanation:

Rounding generally follows the 5/4 rule - round up for a 5 and down for a 4. Per Meave60's comment, ONLY the digit to the right of the rounding space is considered.

My previous answer "rolling up" the digits was incorrect - sorry!

Here are a couple of good explanations:

56 cents

#### Explanation:

We have 56 cents + 0.479 cents

so the 'cut off' point is the red part

$\textcolor{red}{56} \textcolor{g r e e n}{.479}$

We look at the first digit only that is immediately to the right of the cut off point. In this case it is the four $\to \textcolor{g r e e n}{4}$

This is the rule:
If this digit is less than 5 we do not change the red part.
If the digit is 5 or more we increase the red part by 1.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$\textcolor{b r o w n}{\text{Example}}$

Making up a value I choose $\textcolor{red}{2} \textcolor{g r e e n}{.301}$
As the $\textcolor{g r e e n}{3}$ is less than 5 we do not change the red part. So rounded to the nearest whole number we have: $\textcolor{red}{2.0}$ to 0 decimal places

Making up a another value I choose $\textcolor{red}{2} \textcolor{g r e e n}{.601}$
As the $\textcolor{g r e e n}{6}$ is more than or equal to 5 we increase the red part by 1. So rounded to the nearest whole number we have: $\textcolor{red}{3.0}$ to 0 decimal places
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$\textcolor{b r o w n}{\text{Back to the question}}$

The $\textcolor{g r e e n}{4}$ from $\textcolor{red}{56} \textcolor{g r e e n}{.479}$
is less than 5 so we do not change the red part.

Answer $\to 56$
