In This Book

This manual is organized as follows:

Chapter 1: Provides an overview of the basic principles involved in writing floating-point programs and of the HP-UX math libraries used by most floating-point applications.
Chapter 2: Provides an overview of the IEEE Standard for Binary Floating-Point Arithmetic, the standard on which HP floating-point behavior is based.
Chapter 3: Describes the factors that can cause the results of floating-point computations to vary from one system to another or even from one execution to another.
Chapter 4: Describes the math libraries available with the HP-UX operating system on HP 9000 platforms.
Chapter 5: Describes the methods you can use to manipulate the floating-point status register.
Chapter 6: Describes how to enable and handle floating-point traps.
Chapter 7: Describes techniques for obtaining the best possible floating-point performance.
Appendix A: Describes the C math library.
Appendix B: Describes the Fortran math library.
Appendix C: Provides a checklist to help you locate possible causes of a floating-point programming problem.
Glossary: Defines the terms used in this manual.
