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 <p>In this example:</p>
<ul>
<li>fixed disables scientific notation.</li>
<li>x is the initial principal amount.</li>
<li>t is the interest earned.</li>
<li>x   t is the final amount.</li>
</ul>
<p>By using std::fixed, the output will display exact numbers without scientific notation:</p>
<pre class="brush:php;toolbar:false">Bas ana: 3284.78       Son faiz: 1784.78       Son ana: 5069.55
Bas ana: 7193.17       Son faiz: 3908.4        Son ana: 11101.6
