It must be said that you can not use a floating-point implementation in C to verify Mathematica's exact arithmetic, unless you implement a library in C, which enables you to overload all operations in rational arithmetic (I do not mention symbolic computations). You can try to use floating-point numbers in Mathematica to verify an algorithm in C, but then again, I must admit that is very unclear and at least not transparant to the user, when Mathematica sends its floating-point numbers directly to the hardware (like single or double floating-point numbers in C), or handles them in software. ----------------------------Dennis Verschaeren-------------------------- University of Antwerp (Campus UIA) desk 32 3 820 24 03 InfoProc Numeric Interest Group secr 32 3 820 24 01 Dept. of Math. & Comp.
