Re: [Boost-users] Help needed with random exponential_distribution

It seems my problem is with the rand48 function.

With Boost_1_29_0 ---> sizeof(boost::rand48)=8   e.g. the size of a double.

With Boost_1_33_1 ---> sizeof(boost::rand48)=16  e.g. twice the size of a
double.

Because of the truncation that happened with the boost_1_29_0 We were
seeing a correctly randomized distribution for the
exponential_distribution.

Is this a config problem?  If so, where do I fix the "boost::rand48" to be
a "double" again?   I did run the boost ./configure on the Boost_1_33_1
directory before I started using it on the Sun Sparc Solaris8 machine.

Thanks,

Dave
