double operator()(double x, double y) { return pow(x, y); }
};
Definition Defined in the standard header functional, and in the nonstandard backward-compatibility header function.h. Template parameters Parameter Description Default Arg1 The function object's first argument type Arg2 The function object's second argument type Result The function object's result type Model ofAssignable, Default Constructible Type requirements Public base classes None. Members Member Where defined Description first_argument_type unary_function See below. second_argument_type unary_function See below. result_type unary_function See below. New members These members are not defined in the Assignable and Default Constructible requirements, but are specific to unary_function. Member Description first_argument_type The function object's first argument type. This is a typedef for the template parameter Arg1. second_argument_type The function object's second argument type. This is a typedef for the template parameter Arg2. result_type The function object's result type. This is a typedef for the template parameter Result.
