Category: functors Component type: type


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


Each element in V3 will be the quotient 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(),


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 a numeric 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>


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.
divides() Default Constructible The default constructor.

New members

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