当我尝试float用作模板参数时,编译器会为此代码而烦恼,同时int工作正常.

是因为我不能float用作模板参数吗？

#include<iostream>
using namespace std;

template <class T, T defaultValue>
class GenericClass
{
private:
    T value;
public:
    GenericClass()
    {
        value = defaultValue;
    }

    T returnVal()
    {
        return value;
    }
}; 


int main()
{
    GenericClass <int, 10> gcInteger;
    GenericClass < float, 4.6f> gcFlaot;

    cout << "\n sum of integer is "<<gcInteger.returnVal();
    cout << "\n sum of float is "<<gcFlaot.returnVal();

    return 0;       
}

错误:

main.cpp: In function `int main()':
main.cpp:25: error: `float' is not a …
