How to convert the last 3 digits of the number? Numbers will be bigger then 8000.

For example:

From 249439 to 249000?

You can get the last three digits using the modulus operator `%`

, which (for positive numbers) computes the remainder after integer division; for example, `249439 % 1000`

is `439`

.

So to round down to the nearest thousand, you can just subtract those three digits:

```
var rounded = original - original % 1000;
```

(for example, if `original`

is `249439`

, then `rounded`

will be `249000`

).
