title: How to convert exponential value to string format in python?
body: <p>I'm doing some calculations which give very small decimal numbers for example, <code>0.0000082</code></p>
  
  <p>When I'm saving it in a variable, it changes into exponent form. I need the result as a string in the end. So, converting the result using <code>str()</code> is not possible because it keeps the <code>e</code> in the string.
  I need the string to have exactly 8 decimal places. Is there any way to do this while keeping the 8 digit precision intact?</p>
  
  <p>Another example: <code>5.8e-06</code> should be converted to <code>'0.00000580'</code> The trailing zero in the final string is not important.
  I need the string to be used elsewhere. So, this shouldn't be done in the <code>print()</code> function.</p>
