@[HonmaMeiko_](/user/619811) .0lf是四舍五入，直接强制int即可。
```cpp
#include <cstdio>
#include <iostream>
#include <algorithm>
using namespace std;
int numbers;
int main() {
double m = 0, t = 0, s = 0;
cin >> m >> t >> s;
double realTime = m * t;
if (realTime < s) {
printf("0");
} else {
double v = 1 / t;
numbers = m - v * s;
printf("%d", numbers);
}
return 0;
}
```
