COMP6021 Class 02.3 - Negative Numbers

We played Binary Bingo, but the winner wasn't aware that he had won.

We looked at One's Complement and Two's Complement representations of integers. I explained why they were better that sign & magnitude representations. We looked at using offset binary for awkward situations.  I briefly mentioned IEEE Floating Point, but we won't be going into that. 

We began our look at representing text. I outlined the problems facing Outpost 19 after an attack by the zombie hoard, and asked students to devise an efficient communication system for the traffic lights.
