15.1.1 Floating-Point Number Caveats

This section describes some of the issues involved in using floating-point numbers.

There is a very nice paper on floating-point arithmetic by David Goldberg, “What Every Computer Scientist Should Know About Floating-point Arithmetic,” ACM Computing Surveys 23, 1 (1991-03), 5-48. This is worth reading if you are interested in the details, but it does require a background in computer science.
