std::minus(3) C++ Standard Libary std::minus(3) NAME std::minus - std::minus Synopsis Defined in header <functional> template< class T > (until C++14) struct minus; template< class T = void > (since C++14) struct minus; Function object for performing subtraction. Effectively calls opera- tor- on two instances of type T. Specializations The standard library provides a specialization of std::minus when T is not specified, which leaves the parameter types and return type to be deduced. (since C++14) minus<void> function object implementing x - y deducing argument and (C++14) return types (class template specialization) Member types Type Defini- tion result_type (deprecated in C++17)(removed in C++20) T first_argument_type (deprecated in C++17)(removed in C++20) T second_argument_type (deprecated in C++17)(removed in C++20) T These member types are obtained via publicly inheriting (until C++11) std::binary_function<T, T, T>. Member functions operator() returns the difference between two arguments (public member function) std::minus::operator() T operator()( const T& lhs, const T& rhs ) const; (until C++14) constexpr T operator()( const T& lhs, const T& rhs ) const; (since C++14) Returns the difference between lhs and rhs. Parameters lhs, rhs - values to subtract from one another Return value The result of lhs - rhs. Exceptions May throw implementation-defined exceptions. Possible implementation constexpr T operator()(const T &lhs, const T &rhs) const { return lhs - rhs; } http://cppreference.com 2022.07.31 std::minus(3)
