Logical operator

Question

#include <iostream>
using namespace std;
int main() {
double a=0.1;
double b=0.2;
double c=0.3;
cout<<(a+b==c);
return 0;
}
Why is the result 0,bros ? I think the output is 1 because all variables are double type.

Answer 1

Samsil Arefeen Ok understood.
Le Huu Dai Actually computer returns 0.1 + 0.2 = 0.30000000000004 that's why output is 0.
