To round a number to the nearest 5, call the `Math.round()` function, passing it the number divided by `5` and multiple the result by `5`. The `Math.round` function takes a number, rounds it to the nearest integer and returns the result.

## Round a Number to the Nearest 5

**To round a number to the nearest 5, call the `Math.round()` function, passing
it the number divided by `5` and multiply the result by `5`. The `Math.round`
function takes a number, rounds it to the nearest integer and returns the
result.**

```javascript:index.js
function roundNearest5(num) {
  return Math.round(num / 5) * 5;
}

console.log(roundNearest5(12)); // 👉️ 10
console.log(roundNearest5(13)); // 👉️ 15
console.log(roundNearest5(-13)); // 👉️ -15
console.log(roundNearest5(-12)); // 👉️ -10
console.log(roundNearest5(32.4)); // 👉️ 30
console.log(roundNearest5(32.5)); // 👉️ 35
```

We used the
[Math.round](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/round)
function to round a number to the nearest integer.

Here are some examples of using the `Math.round` function.

```javascript:index.js
console.log(Math.round(4.49)); // 👉️ 4
console.log(Math.round(4.5)); // 👉️ 5
console.log(Math.round(40)); // 👉️ 40
console.log(Math.round(-44.5)); // 👉️ -44
console.log(Math.round(-44.51)); // 👉️ -45

console.log(Math.round(null)); // 👉️ 0
```

<Alert type="error">
  When the <code>Math.round</code> function is invoked with a <code>null</code>{' '}
  value, it returns <code>0</code>.
</Alert>

This is how we solved it in a step-by-step manner.

```javascript:index.js
console.log(12 / 5); // 👉️ 2.4
console.log(13 / 5); // 👉️ 2.6

console.log(Math.round(12 / 5)); // 👉️ 2
console.log(Math.round(13 / 5)); // 👉️ 3

console.log(Math.round(12 / 5) * 5); // 👉️ 10
console.log(Math.round(13 / 5) * 5); // 👉️ 15
```

This is a two step process:

1. Divide the number by `5` and round the result to the nearest integer.
2. Multiply the result by `5` to get the number rounded to the nearest `5`.

The `Math.round` function handles all the heavy lifting for us.
