版主这么一说，偶又发现了有意思的....但是怎么解释呢？
运行这个感觉不深入了解c++会有很多头疼的事情...

It is ok now.
[CODE]#include <iostream>
using namespace std;
int main()
{
float a=50.25f,b=11.17f;
//cout.setf(ios_base::fixed,ios_base::floatfield);
cout << "a = " << a << endl
<< "b = " << b << endl
<< "a + b = " << a + b
<< endl ;
return 0;
}

[/CODE]
