A C++ Class Library for Extended Scientific Computing

C-XSC is a tool for the development of numerical algorithms delivering highly accurate and automatically verified results. It provides a large number of predefined numerical data types and operators. These types are implemented as C++ classes. Thus, C-XSC allows high-level programming of numerical applications in C and C++. The C-XSC package is available for many computers with a C++ compiler translating the AT&T language standard 2.0.

Springer-Verlag has published a language description of C-XSC.

A short description of C-XSC (20 pages) is available here (Postscript gnu-zipped).
