C++ relative numbers

Question

here there is my programm but when a result should be negative the programm show 0, further more i have only round numbers, and i would like to have some specific numbers. Someone can help me please ;)

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;

int main() {
int a;
int b;
int c;
cout<< "Entrez a\n";
cout<< "Entrez b\n";
cout<< "Entrez c\n";
cin >> a >> b >> c;
int delta = (b*b)-(4*(a*c));
int racine_carre_de_delta = sqrt(delta);

cout<< delta<<endl;

if (delta > 0) {
int x1= ((-b-racine_carre_de_delta)/(2*a));
int x2= ((-b+racine_carre_de_delta)/(2*a));
cout<< "Deux solutions\n";
cout<< fixed<< setprecision (9)<< x1<<endl;
cout<< fixed<< setprecision (9)<< x2<<endl;
}
if (delta == 0) {
int x1bis= (-b/(2*a));
cout<< "Une solution\n";
cout<< fixed<< setprecision (9)<< x1bis<<endl;
}
if (delta < 0){
cout << "Pas de soltution";
}

return 0;
}

Answer 1

a clue i thinks better lol

Unsigned Integer Types unsigned short, unsigned int, unsigned long, and unsigned long long there is signed types.

as for accuracy can an int hold a decimal place like a real number a floating decimal place.

rounded up or down may be implicated by the types of data we use i guess lol
