[Error] invalid operands of types 'double' and 'double' to binary 'operator%'

[Stoney L]

Hey, can you guys tell me how to get this correct?It says "[Error] invalid operands of types 'double' and 'double' to binary 'operator%' "But I don't know what the error is!Under this sentence is my code:

#include<bits/stdc++.h>
using namespace std;
double n,x,y,a;
int main(){
	cin>>n>>x>>y;
	a=ceil(y/x);
	if(y%x==0)cout<<n-y/x<<endl;
	else cout<<n-a<<endl;
	return 0;
}

(From the angry writer:Ahhh.... ..This DUMBDUDE code......)

[Error] invalid operands of types 'double' and 'double' to binary 'operator%'

% works with integral operands.

Use fmod https://www.cplusplus.com/reference/cmath/fmod/

Also, decimal comparisons may not be accurate.
