[Boost-users] [random] Cauchy distribution

Hi, I have the following code boost::mt19937 rng; boost::cauchy_distribution< double > cauchy( 0.0 , 0.1 ); for( size_t i=0 ; i<16 ; ++i ) { std::cout << cauchy( rng ) << " "; } which produced this sequence : 76513.4 4.3467e+06 -254805 -1.63299e+06 -6.96405e+06 233243 214884 883827 471904 268253 648798 140314 1.43562e+06 653319 -582905 91567.6 I think these number are much to high. The standard deviation should be 0.1. Does anyone knows what went wrong? Is this my failure? I use boost 1.46 and gcc 4.5.2.
