How to Eliminate Scientific Notation in C cout When Displaying Large Numbers?

Eliminating Scientific Notation in C cout

When dealing with large numerical values, C 's cout stream can output numbers using scientific notation (e.g., 1.23e 06). However, in certain situations, it is preferable to display numbers with precise decimal representation. Here's how to accomplish this:

Consider the following code that calculates compound interest:

<code class="cpp">double x = 1500;
for (int k = 0; k<10 ; k++) {
    double t = 0;
    for (int i = 0; i<12; i++) {
        t += x * 0.0675;
        x += x * 0.0675;
    }
    cout << "Bas ana: " << x << "\tSon faiz: " << t << "\tSon ana: " << x + t << endl;
}</code>

This code produces output in scientific notation, as seen in the following excerpt:

Bas ana: 1.73709e+006   Son faiz: 943845        Son ana: 2.68094e+006
Bas ana: 3.80397e+006   Son faiz: 2.06688e+006  Son ana: 5.87085e+006

To output numbers with exact decimal representation, utilize the std::fixed stream manipulator. This manipulator forces cout to use fixed-point notation for subsequent numeric output. Modify the code as follows:

<code class="cpp">cout << fixed << "Bas ana: " << x << "\tSon faiz: " << t << "\tSon ana: " << x + t << endl;</code>

This modification produces the desired output with precise decimal representation:

Bas ana: 1737090    Son faiz: 943845        Son ana: 2680935
Bas ana: 3803970    Son faiz: 2066880       Son ana: 5870850
