NAME
divides - Returns the result of dividing its first argument by its
second.
SYNOPSIS
#include <functional>
template <class T>
struct divides;
DESCRIPTION
divides is a binary function object. Its operator() returns the
result of dividing x by y. You can pass a divides object to
any algorithm that requires a binary function. For example, the
transform algorithm applies a binary operation to corresponding
values in two collections and stores the result. divides would be
used in that algorithm in the following manner:
vector<int> vec1;
vector<int> vec2;
vector<int> vecResult;
transform(vec1.begin(), vec1.end(),
vec2.begin(), vecResult.begin(),
divides<int>());
After this call to transform, vecResult[n] will contain vec1[n] divided
by vec2[n].
