#include<bits/stdc++.h>
using namespace std;
int main(){
    double a;
    cin>>a;
    cout<<(int)a;
}

数据范围要开long double

by xxx听取AC声一片 @ 2022-03-30 17:50:22

而且double我没记错是双精度浮点数，float才是单精度浮点数

啊呸，看错了，数据范围很大，要用long long (int)a 应改为 (long long)a

十年OI一场空，不开long long见祖宗

int main() {
    int a;
    scanf("%d",&a);
    printf("%d",a);
}
