floating-point arithmetics

Hi all,

   I am experiencing a problem with high precision integer arithmetic in ROOT.    After e^{20}, fmod() function seems to lose precision due to floating point error I presume.

   I wonder if there exists a class manipulating large integer, or floating point arithmetic in general , something similar to GMP (GNU Multiple Precision Arithmetic Library).

   If not, it should be rather helpful, if such a feature was included in forthcoming versions.
Friendly,
