operator==,!=(std::negative_binomial_distribution)

friend bool operator==( const negative_binomial_distribution& lhs,
                        const negative_binomial_distribution& rhs );

friend bool operator!=( const negative_binomial_distribution& lhs,
                        const negative_binomial_distribution& rhs );

Compares two distribution objects. Two distribution objects are equal when parameter values and internal state is the same.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::negative_binomial_distribution<ResultType> is an associated class of the arguments.
