A.2.126.1 Expansions

The -xia option is a macro that expands to -fsimple=0 -ftrap=%none -fns=no -library=interval. If you use intervals and override what is set by -xia by specifying a different flag for -fsimple, -ftrap, -fns or -library, you may cause the compiler to exhibit incorrect behavior.

Interactions

To use the interval arithmetic libraries, include <suninterval.h>.

When you use the interval arithmetic libraries, you must include one of the following libraries: libC, Cstd, or iostreams. See -library for information on including these libraries.

Warnings

If you use intervals and you specify different values for -fsimple, -ftrap, or -fns, then your program may have incorrect behavior.

C++ interval arithmetic is experimental and evolving. The specifics may change from release to release.
