• Multi-byte Integer Types
• Signed Integers – cover 2s compliment extensively, but mention 1s compliment and sign-magnitude, because these still come out of some sensors and FPGAs.
• Unsigned Integers
• Floating Point (I doubt many people will want to use it in a PIC, but they may be given it and need to deal with it.)
