@[ivyjiao](/user/578029) 这题**不用**浮点数?
_“输入一个**单精度浮点数**,将其向零舍入到整数。说明:向零舍入的含义是,正数向下舍入,负数向上舍入。”_
是不是**看错题了**???

@[huzhage](/user/827877) **确实**,单精度有 6 位小数,双精度有 15 位小数,本题**第4测试点15位**。。。

```
#include<iostream>
using namespace std;
int main(){
long long x;
cin>>x;
cout<<x;
}
```

@[Chenzhehao](/user/550933) 哈哈哈,int 自动舍入不知道吗

@[A_Passing_Creeper](/user/540363) 艹6,我用的字符串

@[huzhage](/user/827877) 本SB字符串做法
```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
string s;cin >> s;
for(int i = 0; i < s.size(); i++){
if(s[i] == '.') return 0;
else cout << s[i];
}
}
```
