Hacker's Delight

Hacker's Delight by Henry S. Warren, Jr., is a book published by Addison-Wesley Professional on 17 July 2002. It discusses a variety of programming algorithms for common tasks involving integer types, often with the aim of performing the minimum number of operations or replacing slow operations by faster ones (e.g., converting a divide by a constant into a multiply by another constant that gives the same result).

The second edition was released in 2013. It had new chapters on cyclic redundancy code and other error correcting codes. It also had a new appendix containing graphs of discrete functions.
