如何得到除法的浮点结果？

虽然我将平均数组定义为float。

int main()
{    
const int Number = 20; 
int Fibonacci[Number]; 
float average[Number];
for ( int i =0; i <= Number; i++ )
{
    if ( i == 0 ) 
       {Fibonacci[i] = 0;}
    else if ( i == 1 ) 
       {Fibonacci[i] = 1;}
    else 
       {Fibonacci[i] = Fibonacci[i -1] + Fibonacci[i -2];

        //average[i] = (Fibonacci[i -1] + Fibonacci[i -2])/2 ;   
       }
}

cout<< "The first 20 Fibonacci series numbers are: \n";
for ( int i = 1; i <= Number; i++)
{    cout<< Fibonacci[i]<<endl;

}



cout<< "The average adjacent array numbers are: \n";
for ( int i = 3; i <= Number; i++)
{   average[i] = (Fibonacci[i]/2);
    //cout.precision(0);

问题就在这里

    cout<< average[i]<<endl;     <-----here the problem!!
}

return 0;
}

我很感激任何帮助。 提前谢谢你。
