@[guang_zi_guei_ji](/user/1068448) 试试把所有的变量都改成float

@[szlh_XJS](/user/672757) 不行啊，要取余

@[guang_zi_guei_ji](/user/1068448) 改成double？

```
#include<iostream>
using namespace std;
int main()
{
int n,k,a=0,b=0;
double suma=0,sumb=0;
cin>>n>>k;
for(int i=1;i<=n;i++){
if(i%k==0){
a++;
suma+=i;
}
else if(i%k!=0){
b++;
sumb+=i;
}
}
printf("%.1lf %.1lf",suma/a,sumb/b);
return 0;
}
```
