我在Laravel项目中使用MongoDB，遇到了一个问题：我注意到字段age、weight、height和concluded用引号括起来，使它们看起来像字符串：

{
  "_id": {
    "$oid": "64b41ba740f8fc543547b2d3"
  },
  "name": "Michael",
  "age": "20",
  "height": "1.89",
  "weight": "78.79",
  "begin": "2023-07-16",
  "finish": "2023-07-28",
  "concluded": "true",
  "updated_at": {
    "$date": "2023-07-16T16:33:22.423Z"
  },
  "created_at": {
    "$date": "2023-07-16T16:32:39.375Z"
  }
}

字符串
我期望：

{
  "_id": {
    "$oid": "64b41ba740f8fc543547b2d3"
  },
  "name": "Michael",
  "age": 20,
  "height": 1.89,
  "weight": 78.79,
  "begin": "2023-07-16",
  "finish": "2023-07-28",
  "concluded": true,
  "updated_at": {
    "$date": "2023-07-16T16:33:22.423Z"
  },
  "created_at": {
    "$date": "2023-07-16T16:32:39.375Z"
  }
}
