Environment

• Dubbo version: 2.8.5
• Operating System version: mac os 10.14
• Java version: 1.8.0_191

Steps to reproduce this issue

1. dubbo provider返回类型为Float或者带有float的时候：

Float test();

implements为：

@Override
    public Float test() {
        return 99.8F;
    }

2. 消费者为泛化调用：

    Object result = genericService.$invoke(methodName, parameterTypes, params); //泛化调用刚刚的方法

Expected Result

结果不出意料的化应当是99.8

Actual Result

实际得到的是99.80000305175781

当我把上诉的Float类型改成Double的时候却不会出现这个情况（泛化调用float类型精度会丢失？）
