建议一：用例编号FCJT_sendTransaction_020070，发起一个发送代币的交易，如果交易额是负数，返回的提示信息是"value must be integer type and >= 0"。但实际上此处交易额是可以为正小数的，所以这个提示信息可以改为"value must be >= 0"。

    "jsonrpc": "2.0",
    "method": "jt_sendTransaction",
    "params": [
        {
            "from": "jPdx7mG595P6CowtGYbxRkik9HdWUWtB2J",
            "secret": "shhquPeZm7uQ6Rvjrqn6L2cR6H33u",
            "to": "js3MF5kQkTG6NBVj9HEiw9cFe4ckNvMYGg",
            "value": "-0.1/AAT1",
            "memos": [""]
        }
    ],
    "id": 1
}

    "error": {
        "count": 1,
        "description": "The compound error.",
        "information": "1 errors"
    },
    "id": 1,
    "jsonrpc": "2.0",
    "result": [
        {
            "error": {
                "description": "Invalid.",
                "information": "value must be integer type and >= 0",
                "message": {
                    "from": "jPdx7mG595P6CowtGYbxRkik9HdWUWtB2J",
                    "memos": [
                        ""
                    ],
                    "to": "js3MF5kQkTG6NBVj9HEiw9cFe4ckNvMYGg",
                    "value": "-0.1/AAT1"
                }
            },

        }
    ],
    "status": 1000,
    "type": "tedCOMPOUND"
}

建议二：用例编号FCJT_sendTransaction_031010，发行代币时，如果total_supply不是字符串，而是一个正整数，返回的提示信息是"total_supply must be integer type"。这种情况的提示信息可以改为"total_supply must be string type"。

            "decimals": "6",
            "total_supply": 9,  <== 非字符串
            "local": false,
            "flags": 65536
        }
    ],
    "id": 1
}

{
    "error": {
        "count": 1,
        "description": "The compound error.",
        "information": "1 errors"
    },
    "id": 1,
    "jsonrpc": "2.0",
    "result": [
        {
            "error": {
                "description": "Invalid.",
                "information": "total_supply must be integer type",
                "message": {
