friend bool operator!=( const exponential_distribution& lhs, const exponential_distribution& rhs );
|(2)|| (since C++11) |
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::exponential_distribution<ResultType> is an associated class of the arguments.
