title: Trying to understand one's complement
body: <p>I was going through some problems so that I could understand one's complement and had a question about one similar to this.</p>
  
  <p>If this binary number is in one's complement format already:
  1010 1111 1111</p>
  
  <p>What decimal number does it represent?</p>
  
  <hr>
  
  <p>Am I correct in this process? 1010 1111 1111 has a negative sign (far left bit).</p>
  
  <p>Then take the complement: 0101 0000 0000 = 1280</p>
  
  <p>So it represents -1280? Or is this completely wrong.</p>
