PXSC

PASCAL-XSC: PASCAL for Extended Scientific Computing.

This is the dialect of Pascal developed in Germany in "Institut für Angewandte Mathematik".

The programming language PASCAL-XSC was developed to supply a powerful tool for the numerical solution of scientific problems based upon a properly defined and implemented computer arithmetic in the usual spaces of numerical computation. The main concepts of PASCAL-XSC are

• ISO Standard PASCAL
• Universal operator concept (user-defined operators)
• Functions and operators with arbitrary result type
• Overloading of procedures, functions, and operators
• Access to subarrays
• String concept
• Controlled rounding
• Optimal (exact) scalar product
• Predefined type dotprecision (a fixed point format to cover the whole range of floating-point products)
• Additional arithmetic built-in types such as complex, interval, rvector, rmatrix, etc.
• Highly accurate arithmetic for all built-in types
• Highly accurate elementary functions
• Exact evaluation of expressions within accurate expressions (#-expressions)
