Decimal in elastic

[Suren]

if i have float field in elastic and give value 9999999.9999999 it rounds it to 10000000 how can i put decimal value without rounding ?

I wonder if scaled float could help.
But anyway I'd read this page. https://www.elastic.co/guide/en/elasticsearch/reference/current/number.html

DELETE /test3

PUT /test3
{
  "mappings": {
    "wildcardtest3": {
      "properties": {
        "num": {
          "type": "scaled_float",
          "scaling_factor": 1000000
        }
      }
    }
  }
}

PUT test3/test3/2
    {
      "num": 999999999999.999999
    }` 

I tried this way by documentation expected result must be all 9s but it rounds number to 1000000000000

If you are testing that in Kibana dev console that might be a Kibana "bug" (or behavior).

If you try to format:

PUT test/_doc/1
{
  "num": 999999999999.999999
}

You will see that Kibana transforms that number to:

PUT test/_doc/1
{
  "num": 1000000000000
}

I suspect that Kibana (or the browser) does that transformation before sending to elasticsearch.

Here is a workaround I found. Note that I'm using also here double instead of float.

DELETE /test
PUT /test
{
  "mappings": {
    "_doc": {
      "properties": {
        "num": {
          "type": "double"
        }
      }
    }
  }
}

PUT test/_doc/1
{
  "num": "999999999999.999999"
}
GET test/_doc/1
