How to Prevent C cout from Displaying Numbers in Scientific Notation?

How to Disable Scientific Notation in C cout

When displaying double-precision floating-point numbers using cout in C , you may encounter scientific notation, which uses exponents to represent large or small numbers. This can make the output difficult to read. To disable scientific notation and display exact numbers, follow these steps:

Use the std::fixed stream manipulator. This manipulator instructs cout to use fixed-point notation, which represents numbers as decimals. The stream manipulator is used as follows:

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

In this example:

• fixed disables scientific notation.
• x is the initial principal amount.
• t is the interest earned.
• x t is the final amount.

By using std::fixed, the output will display exact numbers without scientific notation:

Bas ana: 3284.78       Son faiz: 1784.78       Son ana: 5069.55
Bas ana: 7193.17       Son faiz: 3908.4        Son ana: 11101.6
Bas ana: 15752        Son faiz: 8558.8        Son ana: 24310.8
Bas ana: 34494.5       Son faiz: 18742.5       Son ana: 53237
Bas ana: 75537.8       Son faiz: 41043.3       Son ana: 116581
Bas ana: 165417       Son faiz: 89878.7       Son ana: 255295
Bas ana: 362238       Son faiz: 196821        Son ana: 559059
Bas ana: 793246       Son faiz: 431009        Son ana: 1224255
Bas ana: 1737093       Son faiz: 943845        Son ana: 2680938
Bas ana: 3803973       Son faiz: 2066883       Son ana: 5870856
