2. Introduction – Datalab
Objective — to become more familiar with bit-level representations of integer and floating point numbers
Approach — solve a series of “programming puzzles”
Each forces you to manipulate the bits of an integer or floating point number
Limited as to which operations you can use
Graded on correctness, performance, and style!
