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()
{
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;
