c++ float precision code example

Example 1: setprecision in c++

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

int main()
{
   int num = 45;
  cout << "it is: " << fixed << setprecision(2) << num << " the end"<< endl;
  
  return 0;
}

Example 2: how to print 5 precision float in c++

#include <iostream>
#include <cstdio>
using namespace std;

int main() 
{
    // This code helps you to print a number with desired decimal
    double Number=10.3454;
    printf("%.3lf",Number);

    return 0;
}

Example 3: how to make floats output with 2 decimals c++

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

int main()
{
	float x=10.3445f;
	
	cout<<fixed<<setprecision(5)<<x<<endl;
	cout<<fixed<<setprecision(2)<<x<<endl;
	cout<<fixed<<setprecision(3)<<x<<endl;
	cout<<fixed<<setprecision(0)<<x<<endl;
	
	return 0;
}

Example 4: how to make a float in C++

public float whatYourFloatIsCalled = 0;
public float whatIsYourFloat;

Example 5: float in c++

float contains less storage than a double. 
float p = 25.0;
double p = 25.0;
