It did have some float point evaluation problem with new version of libraries.
In my case it did not even reach that far due to errors in clifford_moebius_map.
I have replaced the paper at arXiv.org already with new version
Actually, the code in the paper was OK (modulo minor issues like missing #include <cmath>, BTW, it is better to NOT #include <math.h> in C++ code unless you *really* know what are you doing).
which works with current GiNaC CVS.
Old version works with HEAD too. I've missed that comment about version (moreover, the abstract says 1.3 is good enough). So, the actual problem is that clifford_moebius_map in GiNaC 1.3 is broken. Thanks, Alexei -- All science is either physics or stamp collecting.
