std::modulus(3) C++ Standard Libary std::modulus(3) NAME std::modulus - std::modulus Synopsis Defined in header <functional> template< class T > (until C++14) struct modulus; template< class T = void > (since C++14) struct modulus; Function object for computing remainders of divisions. Implements operator% for type T. Specializations The standard library provides a specialization of std::modulus when T is not specified, which leaves the parameter types and return type to be deduced. (since C++14) modulus<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 returns the remainder from the division of the first ar- gument by the operator() second argument (public member function) std::modulus::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 remainder of the division of lhs by rhs. Parameters lhs, rhs - values to divide one by 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; } See also fmod fmodf remainder of the floating point division operation fmodl (function) (C++11) (C++11) remainder remainderf remainderl signed remainder of the division operation (C++11) (function) (C++11) (C++11) http://cppreference.com 2022.07.31 std::modulus(3)
