how to print 5 precision float in c++

To print a floating-point number with 5 decimal places in C++, you can use the std::cout stream and the std::setprecision manipulator from the <iomanip> header. Here are the steps:

  1. Include the <iostream> and <iomanip> headers at the beginning of your code to use the necessary input/output and manipulation functions.
  2. Use the std::cout stream to output the floating-point number.
  3. Use the std::setprecision manipulator to set the desired precision for the output.
  4. Pass the desired precision as an argument to std::setprecision, specifying the number of decimal places you want to display. In this case, it would be 5.
  5. Make sure to include the std::fixed manipulator if you want to display the number with a fixed number of decimal places after the decimal point.

Here's an example code snippet that demonstrates how to print a floating-point number with 5 decimal places in C++:

#include <iostream>
#include <iomanip>

int main() {
    double number = 3.14159;
    std::cout << std::fixed << std::setprecision(5) << number << std::endl;
    return 0;
}

In this example, the output will be 3.14159, with 5 decimal places.
