Before You Begin |
This manual documents the C++ interface to the C++ interval arithmetic library provided with the Sun Studio C++ compiler.
This is a reference manual intended for programmers with a working knowledge of the C++ language, the Solaris operating environment, and UNIX commands.
This book contains the following chapters:
Chapter 1 describes the C++ interval arithmetic support goals and provides code samples that interval programmers can use to quickly learn more about the C++ interval features. This chapter contains the essential information to get started writing interval code using C++.
Chapter 2 is a complete description of the C++ interval arithmetic library interface.
"Glossary" contains definitions of interval terms.
This book is not an introduction to intervals and does not contain derivations of the interval innovations included in the interval arithmetic C++ library. For a list of sources containing introductory interval information, see the Interval Arithmetic Readme.
The interval literature is large and growing. Interval applications exist in various substantive fields. However, most interval books and journal articles either contain these algorithms, or are written for interval analysts who are developing new interval algorithms. There is not yet a book titled "Introduction to Intervals."
The Sun Studio C++ compiler is not the only source of C++ support for intervals. Readers interested in other well known sources can refer to the following books:
For a list of technical reports that establish the foundation for the interval innovations implemented in class interval, see References. See the Interval Arithmetic Readme for the location of the online versions of these references.
Additional interval information is available at various web sites and by subscribing to email lists. For a list of online resources, refer to the Interval Arithmetic Readme.
A detailed bibliography and interval FAQ can be obtained online at the URLs listed in the Interval Arithmetic Readme.
To discuss interval arithmetic issues or ask questions about using interval arithmetic, a mailing list has been constructed. Anyone can send questions to this list. Refer to the Interval Arithmetic Readme for instructions on how to subscribe to this mailing list.
To report a suspected interval error, send email to the following address:
Include the following text in the Subject line of the email message:
FORTEDEV "7.0 mm/dd/yy" Interval
where mm/dd/yy is the month, day, and year of the message.
All code examples in this book are contained in the following directory:
http://www.sun.com/forte/cplusplus/interval
The name of each file is cen-m.cc, where n is the chapter in which the example occurs and m is the number of the example. Additional interval examples are also provided in this directory.
The "pipe" or "bar" symbol separates arguments, only one of which may be chosen. |

The colon, like the comma, is sometimes used to separate arguments. |

The compilers and tools and their man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the compilers and tools, you must have your PATH environment variable set correctly (see Accessing the Compilers and Tools). To access the man pages, you must have the your MANPATH environment variable set correctly (see Accessing the Man Pages.).
For more information about the PATH variable, see the csh(1), sh(1), and ksh(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH variable and MANPATH variables to access this release, see the installation guide or your system administrator.
Use the steps below to determine whether you need to change your PATH variable to access the compilers and tools.
|
1. Display the current value of the PATH variable by typing the following at a command prompt.
2. Review the output to find a string of paths that contain /opt/SUNWspro/bin/.
If you find the path, your PATH variable is already set to access the compilers and tools. If you do not find the path, set your PATH environment variable by following the instructions in the next procedure.
|
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your PATH environment variable. If you have Sun ONE Studio software or Forte Developer software installed, add the following path before the paths to those installations.
Use the following steps to determine whether you need to change your MANPATH variable to access the man pages.
|
1. Request the dbx man page by typing the following at a command prompt.
If the dbx(1) man page cannot be found or if the man page displayed is not for the current version of the software installed, follow the instructions in the next procedure for setting your MANPATH environment variable.
|
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your MANPATH environment variable.
The Sun Studio 8 integrated development environment (IDE) provides modules for creating, editing, building, debugging, and analyzing the performance of a C, C++, or Fortran application.
The IDE requires the Core Platform component of Sun Studio 8. You must set the SPRO_NETBEANS_HOME environment variable to the location where the Core Platform component is installed or mounted (installation_directory/netbeans/3.5R) if the Core Platform component is not installed or mounted to one of the following locations:
The command to start the IDE is sunstudio. For details on this command, see the sunstudio(1) man page.
