std::modulus

STD：：模数

Defined in header ​​
template< class T > struct modulus;​(until C++14)
template< class T = void > struct modulus;​(since C++14)

用于计算除数的函数对象。实施器operator%类型T...

专门性

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. modulus function object implementing x % y deducing argument and return types (class template specialization)modulusfunction object implementing x % y deducing argument and return types (class template specialization)(since C++14)
modulus<void>function object implementing x % y deducing argument and return types (class template specialization)

成员类型

TypeDefinition
result_type(deprecated in C++17)T
first_argument_type(deprecated in C++17)T
second_argument_type(deprecated in C++17)T

成员函数

operator()returns the remainder from the division of the first argument by the second argument (public member function)

STD：：模数：：操作员%28%29

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)

的除法的其余部分。lhs通过rhs...

参数

lhs, rhs-values to divide one by another

返回值

结果lhs % rhs...

例外

%280%29

可能的实施

ConstT算子%28%29%28 const T&lhs，const T&rhs%29 const{返回lhs%rhs；}

*。

fmodremainder of the floating point division operation (function)
remainder (C++11)signed remainder of the division operation (function)
