title: Unwrapping double to a string in java
body: <p>In Java, for storing large numbers(10^80 to 10^100), we will be using <code>Double</code>. But <code>Double</code> will return in ae^x format where x is exponent value.Is there any way to unwrap it to a string.<br>
  Eg: <code>Double d = 1000000000;</code></p>
  
  <pre><code> Double.toString(d); --&gt; output: 1.0E9.
  </code></pre>
  
  <p>Instead I want it as 1000000000</p>
