[CodeOpen]

float is 7 digit. Isn't it? why out put print out 6 digit?

#include <iostream>
using namespace std;


int main() {
    float a = 1.23456.7; 
    cout << a;
}

You can set the output precision to show more or less digits:

#include <iostream>
#include <iomanip>

int main()
{
   float a = 1.234567;
   
   std::cout.precision(8);
   std::cout << a << std::endl;
   
   std::cout << std::setprecision(5) << a << std::endl;
   
   return 0;
}

1.234567
1.2346
