Accurate Expressions In C-Xsc

Abstract

C-XSC is a programming library for Extended Scientific Compu-ing which support
many data types with high accuracy. However it does not provide the accurate expressions
which are already available in the older language PASCAL-XSC. These expressions have to
be replaced by long loops which are more difficult to understand. Therefore we studied
possibilities how this accurate expressions could be implemented in C-XSC. In this paper we
present possibilities like operator overloading with special result types avoiding rounding errors,
and a small pre-processor which converts accurate expressions to functions calls. We
present results about execution times in comparison with C-XSC. Finally we present some
perspectives for future work.
