Class Description


 Random number generator class (periodicity > 10**14).

 Has a better periodicity than its base class TRandom but is slower.

void GetSeed2(UInt_t &seed1, UInt_t &seed2)
  Set the random generator seeds

Float_t Rndm(Int_t)
  Machine independent random number generator.
  Produces uniformly-distributed floating points between 0 and 1.
  Identical sequence on all machines of >= 32 bits.
  Periodicity > 10**14

void SetSeed(UInt_t seed)
  Set the random generator sequence (not yet implemented)

void SetSeed2(UInt_t seed1, UInt_t seed2)
  Set the random generator seeds
  Note that seed1 and seed2 must be < 2147483647
