Setting the precision

As you already should know you can perform basic data manipulation using arithmetic operators such as addition (+), subtraction (-), division (/), and multiplication (*). Additionally, the modulus operator (%) calculates the remainder of a division.

main.cpp

main.cpp

copy

              
123456789

            
#include <iostream>
#include <iomanip>

int main()
{
    // Uncomment to see the difference
    // std::cout << std::fixed;
    std::cout << std::setprecision(5) << 15.125 * 0.8309 << std::endl;
}

In the example above, floating-point results may occasionally be produced during calculations. To manage the precision of these results, you can use std::setprecision in combination with std::fixed. This allows you to control the number of digits displayed after the decimal point, ensuring consistent precision in your output.

Note

Without std::fixed, std::setprecision controls the total number of digits displayed, including both before and after the decimal points. With std::fixed, the number is displayed in fixed-point notation, keeping the decimal point in a fixed position.

  1. Include <iomanip> to be able to set precision.
  2. Follow the comments to set a precision.
  3. Calculate and output the equivalent of 5 miles in kilometers rounding to one decimal place.

Note

To convert 5 miles to kilometers, you would multiply the number of miles by the conversion factor (1.60934).
