@[jfm0211](/user/1037310) 有个东西叫精度误差

但你这个显然不是精度问题

@[jfm0211](/user/1037310) 你是不是在编译器里删东西了

```cpp
#include <map>
#include <cmath>
#include <vector>
#include <cstdio>
#include <string>
#include <cstring>
#include <iostream>
#include <algorithm>
using namespace std;
int a,b,c;
int main(){
cin>>a>>b>>c;
int d=a/10*2+b/10*3+c/10*5;
cout<<d;
return 0;
}
```
建议这样改一下

谢谢

而且最好别用 ``` float ```，用 ``` double```。
