In the past I’d always used the `Math.round()`

function with floor and such to handle rounding to decimal places, turns out there’s a much simpler way of doing it…

To round to say 3 decimal places, just use the `toFixed()`

method that’s available to any `Number`

. For example:

```
a = 12.34567
a.toFixed(3);
```

The above will return `12.346`

, where the method automatically rounds up the value for you.

This is much shorter than the way I’d been doing the math in the past.
