       param_type param () const
           Returns the parameter set of the distribution.

           & operator<< (std::basic_ostream< _CharT, _Traits > &__os, const std::lognormal_distribution<
           _RealType1 > &__x)
           Inserts a lognormal_distribution random number distribution __x into the output stream __os.
       bool operator== (const lognormal_distribution &__d1, const lognormal_distribution &__d2)
           Return true if two lognormal distributions have the same parameters and the sequences that would be
           generated are equal.
       template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_istream< _CharT, _Traits >
           & operator>> (std::basic_istream< _CharT, _Traits > &__is, std::lognormal_distribution< _RealType1 >
           &__x)
           Extracts a lognormal_distribution random number distribution __x from the input stream __is.

Detailed Description

   template<typename _RealType = double>
       class std::lognormal_distribution< _RealType >" A lognormal_distribution random number distribution.

       The formula for the normal probability mass function is p(x|m,s) = ac{1}{sxt{2i}}
       \xp{-ac{(x} - m)^2}{2s^2}} ]
