title: Convert byte array to decimal
body: <p>I have a byte array and I want to do some manipulation on the basis of the data I have in this array. The content of the byte array is in hexadecimal format. </p>
  
  <pre><code>byte[] signal = message.getFieldValue( "_Decoder Message" ).data();
  </code></pre>
  
  <p>This gives me the byte array with the following content</p>
  
  <pre><code>[ff ff 11 ff ff 82 05 00 13 00 d7 00 fc dc 03 04 00 00 01 00 00 00 1e 00 00 00 52 00 00]
  </code></pre>
  
  <p>Is it possible to convert this byte array to an array which contains values in decimal ?
  Or if I am interested in any specific index how can I convert the value of that index to decimal ?</p>
  
  <p>Let say I want to convert index 18 which in byte array is 01. I am using Java btw.</p>
  
  <p>Thanks</p>
