Homework Help: Two's Complement Representation

  1. Jan 12, 2012 #1
    1. The problem statement, all variables and given/known data
    When determining the two's complement of a decimal number, one converts the decimal to binary, finds the complement of each individual digit, adds one, and there we have it.

    For example,
    -4=1100--->0011+1=0100=+4

    However, when I apply the same logic for -99, I don't seem to get the same type of results
    -99=11100011--->00011100+1=00011101=29
    does anyone see where I am going wrong here?
