What does the dot in the visits field mean in the response to a similarweb api request?

Question

JSON

After a request to the API, I get a response in json format:

"meta": {
        "request": {
            "granularity": "Daily",
            "main_domain_only": false,
            "show_verified": true,
            "format": null,
            "domain": "sait.ru",
            "start_date": "2018-07-01",
            "end_date": "2018-07-31",
            "limit": null,
            "country": "world"
        },
        "status": "Success",
        "last_updated": "2018-07-31"
    },
    "visits": [
        {
            "date": "2018-07-01",
            "visits": 211.6172665827583
        }

How to understand the number of visits? What does the dot mean in visits: 211.6172665827583?
How many visits are there? 211?
Then what do the numbers after the dot mean?

Answer 1

211
you do int(visits)
after the dot - the result of machine learning
is all estimated data, not exact (well, except for those where it is confirmed)
