Detailed Description

template<typename T>
class qmcplusplus::uniform_real_distribution_as_boost< T >

generating real type random numbers [min, max) in a uniform distribution.

This is intended to match the behavior of random::uniform_real_distribution in the boost libraries Its behavor is different from std::uniform_real_distribution which uses std::generate_canonical to generate enough entropy according to the precision of T.
