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.
