Abstract

C-XSC is a programming library for Extended Scientific Computing which supports 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 that are more difficult to understand. Therefore, we studied possibilities how these 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 function calls.
