title: Declare an array of (nullable) doubles?
body: <p>I have this declaration:</p>
  
  <pre><code>double?[] x = 0;
  </code></pre>
  
  <p>I don't know how should I declare the zero because it seems that this is not the right way.</p>
  
  <p>It says: </p>
  
  <blockquote>
    <p>cannot implicitly convert type 'int' to 'double?[]'</p>
  </blockquote>
  
  <p>I have searched on the internet for a solution but everything that I have found didn't help me. Any suggestion?</p>
