title: Convert double to byte[] array
body: <p>How can I convert double to byte array in Java? I looked at many other posts, but couldn't figure out the right way. </p>
  
  <pre><code>Input = 65.43 
  byte[] size = 6
  precision = 2   (this might change based on input)
  
  expected output (byte[]) = 006543
  </code></pre>
  
  <p>Can I do it without using functions like doubleToLongBits()?</p>
