HP-UX Floating-Point Guide

218 Appendix C
Floating-Point Problem Checklist
This appendix provides a checklist of problems you might encounter
when compiling, linking, or running a floating-point application. For
each kind of problem, we list possible reasons for the problem and direct
you to the section of this manual where the reason is discussed.
We divide the problems into two categories:
• Results that are different from those produced when the application
was run previously
• Results that are clearly incorrect or are much less precise than
expected
These categories are not mutually exclusive. If you find your application
produces results that are both different from before and inaccurate, look
at the suggestions in both categories.
Finally, we discuss the possible causes of compiling and linking errors
you may get when you build a floating-point application.
