求大佬指点，我哪错了？

#include <stdio.h>
int main()
{
float money;
scanf("%f", &money);
int beer_max = 0;
int half_num = 0;
for (int i = 1; float(i*(2.3 + 1.9)) <= money; i++) half_num++;
beer_max = half_num;
if (int(money - (half_num * (2.3 + 1.9)) / 1.9) < 1) beer_max--;
int beer_num = 1;
while (beer_num <= beer_max)
{
printf("%d\n", beer_num);
beer_num++;
}
return 0;
}
