Describe the issue:

I have this template:

{
  "index_patterns": [
    "contexts-*",
    "context"
  ],
  "version": 1,
  "template": {
    "aliases": {
      "contexts": {}
    },
    "mappings": {
      "dynamic": "false",
      "properties": {
        "id": {
          "type": "keyword"
        },
        "context": {
          "type": "nested",
          "properties": {
            "dynamic": {
              "type": "object"
            }
          }
        }
      }
    }
  }
}

Field context is nested object. Some values may be BigDecimal.

I trying to insert document with BigDecimal values:

        }
      }
    }
  }
}

I trying to insert document with BigDecimal values:

PUT test-contexts-test/_doc/1
{
  "doc": {
    "id": "lIj0UW9DkyDcZwKkGYkErUnGKMxAUOgo",
    "context": {
      "paramDEPOMNS": -9388376871237831235432123123897817236837128398127315,
      "paramDEPO": 9388376871237831235432123123897817236837128398127315,
      "paramEKS": true,
      "paramCREDO": 6788376871237831235432123123897817236837128398127312.75,
      "paramCREDOMNS": -6788376871237831235432123123897817236837128398127312.75
    }
  }
}

Stored document is:

{
"_index": "test-contexts-test",
"_id": "1",
"_score": 1,
"_source": {
 "doc": {
   "id": "lIj0UW9DkyDcZwKkGYkErUnGKMxAUOgo",
     "context": {
      "paramDEPOMNS": -9388376871237831235432123123897817236837128398127315,
      "paramDEPO": 9388376871237831235432123123897817236837128398127315,
      "paramEKS": true,
      "paramCREDO": 6.788376871237831e+51,
      "paramCREDOMNS": -6.788376871237831e+51
     }
   }
 }
}

As we see, BigInteger values stored in standard notation, but BigDecimal values stored in scientific notation.
