Float value is matched as integer

Elastic Stack Elasticsearch

I've indexed the following document:

  {
                "_index": "index_name",
                "_type": "_doc",
                "_id": "ePvEB-X7TNSfKMdwxOcGTw",
                "_score": 1.0,
                "_source": {
                    "jWVuCKvK": 6.65678676226262E13,
                }
 }

with the corresponding mapping:

   "properties": {
                "jWVuCKvK": {
                    "type": "float"
                }
            }

Field jWVuCKvK has the floating point value: 66567867622626.2

The numbers 66567867622626, 66567867622626.545644 or 66567867622626.5 match this number. Sample search request:

POST /_search

{
   "size":1,
   "terminate_after":30001,
   "query":{
      "bool":{
         "filter":[
            {
               "term":{
                  "jWVuCKvK":{
                     "value":66567867622626,
                     "boost":1.0
                  }
               }
            }
         ],
         "adjust_pure_negative":true,
         "boost":1.0
      }
   },
   "sort":[
      {
         "_shard_doc":{
            "order":"asc"
         }
      }
   ],
   "track_total_hits":-1,
   "pit":{
      "id":"n5qzAwEMdXNlcl9wcm9maWxlFklOZ1VWWUlWUi0yU2hpMS1TUlJ3dlEAFnJQZ3lVTU9DUzR1VXkzbU5EalBJWFEAAAAAAAAAAg0WVkRTeUY5X0JTcWFnVm11a290eXQ1UQABFklOZ1VWWUlWUi0yU2hpMS1TUlJ3dlEAAA==",
      "keep_alive":"10m"
   }
}

I would expect it to match only for value 66567867622626.2. How could I achieve this? Please note that i am using dynamic mapping.
