even if you give an initial value to a float variable, json parsing gives you an initial value. Without the initial value, the result is a little bit like 4.6085e+33.

This is not the case with integers.

In my operating system (win10), when I execute the EXE I generate, as long as the integer is incremented by a small enough number, it can be parsed by cjson。

I suspect this is a matter of the compiler handling floating-point precision

The compiler I use is mingw32 7.4.0。

on trip, I will reply this weekend.

Waiting for your good news。祝你旅途愉快！

另外，这个cjsonobject 怎么识别null和true、false，这也是经常要用到的。好像没有这样的实例函数，只有一个IsEmpty()？

[Bwar]

问题不在.Get(0,fvalue)，在cJSON.c里的print_double()，在你的例子中做了json赋值，赋值时ToString()方法会调用print_double()，而print_double()将.0截掉了，值变成了整数。
另外，你提到的null，我也加入了对null的支持，不过建议能不用null就尽量别用null，null虽然是json属于json标准，但用在C++这种强类型语言里不是太合适，明确一个json value是string、int、float或{}又或[]会更好。

非常感谢，试过了，已经比较完善了，感谢你的辛劳和付出。
