IEEE 754 Floating Point
Given its importance, there is a surprisingly small amount of literature concerning floating point arithmetic. Here are a collection of links to good information about the IEEE 754 standard.- William Kahan's site at Berkeley.
- Original version of What Every Computer Scientist Should Know About Floating-Point Arithmetic by David Goldberg, ACM Computing Surveys, pp. 5-48, vol. 23, no. 1, 1991. Sun's version with Dale Priest's "Differences Among IEEE 754 Implementations" supplement.
- John Hauser's softfloat and testfloat software implementation and test program. Also see his paper Handling floating-point exceptions in numeric programs
- On Properties of Floating Point Arithmetics: Numerical Stability and the Cost of Accurate Computation - Doug Priest
- Nelson Beebe's collection of floating point test software
- Robert Sedgewick and Kevin Wayne's notes give a good overview of some of the practical issues concerning floating point.

Duct tape and WD40
“All of life’s problems can be solved with two things—duct tape and WD40. If it moves and it shouldn’t, you need duct tape. And if it doesn’t move and it should, you need WD40.”—UnknownI dearly love these all purpose tools and usually have both with me. Here are some links to excellent sites about duct tape and WD40.
- The Duck Tape Club lots of good stories here.
- The Duct Tape Guys by Jim and Tim - the duct tape and WD40 guys.
- 3M Duct Tape Site check out the instructions for making the wallet as well as the showcase area.
- Duct tape fashion sells duct tape merchandise such as hats, belts etc.
- Duct tape art gallery one of the worst sites I've come across.
- 2000 uses for WD40
- Frugal living duct tape pages.
- Backpacker Magazine's duct tape review.
