This mini series is all about binary. Over the course of the series, well be building a library that gives us precise control of every bit and operation.
Youll learn how the logical and arithmetic operations work, how different kinds of numbers are encoded, how to set, clear and toggle bits, and how we can create representations of structured binary data.

![Ints, Uints, and Parsing an IP Packet Header [Parser Combinators From Scratch] Episode 7](https://i.ytimg.com/vi/X1sKg0_r4JM/mqdefault.jpg "Ints, Uints, and Parsing an IP Packet Header [Parser Combinators From Scratch] Episode 7
In this episode we finish up with binary parsing by building (almost) arbitrary precision integer and unsigned integer parsers, as well as a parser for extracting ascii strings.
Apologies for my voice in this one - I recorded at the tail end of a chest infection at 6am and it turns out thats when my voice is at its most Barry White.
=[ ℹ About ℹ ]=
During this series we will develop an understanding of the concept of parsing, and build our own parser combinator system from scratch. The system we build will be capable of parsing both binary and text data. Well make use of both object-oriented and function programming principles to develop an effective and intuitive library.
