title: convert a scientific notation/exponential number
body: <p>I am trying to convert a scientific notation/exponential number.</p>
  
  <p>For example :</p>
  
  <p>I get from a API request this number : 4.96E-6</p>
  
  <p>I want to convert it to his normal value 0.00000496.</p>
  
  <p>I searched on the web and tryed a few codes like </p>
  
  <pre><code>$awb = "4.96e-6"; // tried with and without quotes
  $format = sprintf($awb, "%e");
  var_dump($format);
  </code></pre>
  
  <p>it returns : string(7) "4.96E-6"</p>
  
  <pre><code>$awb = 4.96e-6;
  $format = sscanf($awb, "%e");
  var_dump($format);
  </code></pre>
  
  <p>Is returning : </p>
  
  <pre><code>array(1) { [0]=&gt; float(4.96E-6) }
  </code></pre>
  
  <p>Please what should I do ?</p>
  
  <p>Thank you</p>
