C++ Need help to convert large decimal to binary in the program without using arrays/functions. When enter more than 4 digits, it doesn't work.

#include using namespace std;

int main() { float decimal, binary = 0, multiply = 1, remainder;

cout << "Enter decimal number: "; cin >> decimal; cout << "The binary representation of " << decimal ; { while (decimal > 0) { remainder = decimal % 2; binary = binary + ( remainder * multiply ); multiply = multiply * 10; decimal = decimal / 2; } } cout <<" is " << binary << endl; return 0; }
