Regarding wrong ceil and floor values

general

Why there is wrong output of ceil and floor values in this code :

enter code here
#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
int main()
{
float y = 99999980;
float z =-99999980;
ll x = ceil(y);
ll q = floor(z);
cout<<x<<endl<<q<<endl;
}

output is
99999984
-99999984

can any one explain me why such thing is happening ?

4

yes that should be the reason . even when i am printing y and z

it is giving

1e+08
&
-1e+08

Thanks for the explanation !

Hmm. I can think of 3 instances-

  1. When you become a 7 star
  2. When you get a good placement and job from college and your parents start looking for your *dramatic cough*
  3. When you decide to give us all a treat :3 :stuck_out_tongue: :o
