如何为Elasticsearch设置平均聚合精度

Question

我的平均聚集度如下

test "$(cat "$(git rev-parse --git-path HEAD)")" == "ref: refs/heads/master" && echo "HEAD points to master" || echo "HEAD does not point to master"

返回

      ,"aggs": {
      "avgSubmitCost":{
        "avg": {
      "script": "(doc['submitDate'].value.getMillis()-doc['cdate'].value.getMillis())/(60*60*1000)"
    }

      }

  }

但我希望结果是129.2

那么我该如何设置平均聚合的精度以获取结果  谢谢
