Appendix C. Bits, bytes, and data types

Here, I show you basic representations of bytes and briefly characterize how they comprise data types. Additionally, I show a few novel features of C# 7.0, which can be useful for IoT development.

Binary encoding: integral types

A byte can be interpreted as an array of bits—that is, an array of logical values. Formally, each entry of this array encodes the byte value V as the weighted sum:

where bⁱ denotes the bit value (0 or 1), i stands for the bit index, and N is the number of bits. The base (radix) of 2 comes from the fact that a single bit can possess two values. The summation weights increase with ...
