## Explanation

In the example, cell C6 contains this formula:

```
=MROUND(B6,5)
```

The value in B6 is 17 and the result is 15 since 15 is the nearest multiple of 5 to 17.

### Other multiples

As you'd expect, you can use MROUND to round to other multiples as well:

```
=MROUND(number,10) // nearest multiple of 10
=MROUND(number,50) // nearest multiple of 50
=MROUND(number,.05) // nearest 5 cents
```

And so on.

### Force up or down

You can use the CEILING function to force rounding up to the nearest multiple and the FLOOR function to force rounding down to the nearest multiple.
