title: 8-bit to 4-bit integer conversion in C, converting signed int past -8?
body: <p>How would I convert a number like -9 from 8 bit to 4 bit mathematically? What would it convert to? Can someone walk me through it? I'm trying to work it out using C. My current understanding is that signed integers only go to -8, how would a number like -9 be converted from 8 to 4 bit?</p>
