title: How to interpret an 8-bit hex value as unsigned decimal numbers?
body: <p>This is a basic question and probably very easy but I am really confused. </p>
  
  <p>I have an 8-bit hex number 0x9F and I need to interpret this number as an unsigned decimal number. </p>
  
  <p>Do I just convert that to the binary form 1001 1111? and then the decimal number is 159? </p>
  
  <p>I'm sorry if this question is trivial but my professor said I couldn't e-mail him questions and I don't know anyone in my class. He made it sound like when converting from hex to binary that it will be the 2's compliment. So I don't know if I need to convert it back to normal or not before converting to decimal. </p>
  
  <p>We had a signed decimal number and converted it to binary, then took the 2's compliment and converted to hex. Is that only with signed numbers?</p>
