Can you explain me please when expressions (int) (f * 100) and (int)((f+1e-9)*100.0)can differ. (I got AC after using this method, but still can't figure out what  the problem is).

I don't understand !
Why when I read data like integer before and after point :

int price = before * 100 + after -> is wa6

and when I read data like double:

double d;
scanf("%lf, &d);
int price =  (int)(d * 100.0 + 0.1) -> is ok
