title: Most compact way to represent a 32-bit integer in a csv-file
body: <p>I have a lot of (unsigned) integers originating from a measurement. Those are stored in a csv Textfile:</p>
  
  <pre><code>1111492765
  562352
  5362346
  ...
  </code></pre>
  
  <p>Since I have to transmitt this file through a low-bandwidth connection I am looking for a way to save storage-space (chars). </p>
  
  <p>What is the best way to do so beside using a compression (gzip, ...)?</p>
  
  <p>So far representing the 32-bit integers as hexvalues seems promising:</p>
  
  <pre><code>1111492765 = 10 Byte
  </code></pre>
  
  <p>is the same as</p>
  
  <pre><code>4240089D = 8 Byte
  </code></pre>
  
  <p>Note: At the receiving part of the Transmission I can convert the file to anything I like.</p>
