title: Why is int16 type limit 32,768 if 16 bits max is 65,535?
body: <p>Sum of 16 bits all "1" bits will result 65,535:</p>
  
  <p>first byte:
  1(128) 1(64) 1(32) 1(16)        1(8) 1(4) 1(2) 1(1)</p>
  
  <p>second byte:
  1(327,68) 1(16,384) 1(8,192) 1(4,096)    1(2,048) 1(1,024) 1(512) 1(256)</p>
  
  <p>which the decimal would be:</p>
  
  <p>32,768 + 16,384 + 8,192 + 4,096 + 2,048 + 1,024 + 512 + 256 + 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1</p>
  
  <p>total is: 65,535</p>
  
  <p>the max of int16 should be 65,535 and 32,768(which is just 1000 0000 0000 0000)</p>
  
  <p>I can't see how it would be otherwise.</p>
