#### 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.
