modulus<T>


Category: functors	Component type: type

Description

Modulus<T> is a function object. Specifically, it is an Adaptable Binary Function. If f is an object of class modulus<T> and x and y are objects of class T, then f(x,y) returns x%y.

Example

Each element in V3 will be the modulus of the corresponding elements in V1 and V2

const int N = 1000;
vector<double> V1(N);
vector<double> V2(N);
vector<double> V3(N);

iota(V1.begin(), V1.end(), 1);
fill(V2.begin(), V2.end(), 75);

assert(V2.size() >= V1.size() && V3.size() >= V1.size());
transform(V1.begin(), V1.end(), V2.begin(), V3.begin(),
          modulus<int>());

Definition

Defined in the standard header functional, and in the nonstandard backward-compatibility header function.h.

Template parameters

Parameter	Description	Default
`T`	The function object's argument type and result type.

Model of

Adaptable Binary Function, Default Constructible

Type requirements

T must be an integral type; if x and y are objects of type T, then x%y must be defined and must have a return type that is convertible to T. T must be Assignable.

Public base classes

binary_function<T, T, T>

Members

Member	Where defined	Description
`first_argument_type`	Adaptable Binary Function	The type of the first argument: `T`
`second_argument_type`	Adaptable Binary Function	The type of the second argument: `T`
`result_type`	Adaptable Binary Function	The type of the result: `T`
`T operator()(const T& x, const T& y)`	Adaptable Binary Function	Function call operator. The return value is `x % y`.
`modulus()`	Default Constructible	The default constructor.

New members

All of modulus's members are defined in the Adaptable Binary Function and Default Constructible requirements. Modulus does not introduce any new members.
