title: Working with signed numbers other than 10-bit in Excel
body: <p>Is there some way that I am missing within Excel to set the true number of bits in a binary number, or are we stuck with the 10-bit DEC2BIN and BIN2DEC?  10-bit is a strange choice.</p>
  
  <p>I would, ideally, want to be able to choose between a true signed 8-bit or a true signed 16-bit world, and to be able to perform operations with those numbers.  As it stands now, I can't set 11111111 to be -1 instead of 255.  Has anyone else dealt with this?</p>
  
  <p>Thanks in advance.</p>
