    NAME
         modulus
    
          - Returns the remainder  obtained  by  dividing  the  first
         argument by the second argument.
    
    
    
    SYNOPSIS
         #include<functional>
         template <class T>
         struct modulus : public binary_function<T, T, T> ;
    
    
    
    DESCRIPTION
         modulus is a binary function object. Its operator()  returns
         the  remainder resulting from x divided by y. You can pass a
         modulus object to any algorithm that requires a binary func-
         tion.  For example, the transform algorithm applies a binary
         operation to corresponding values  in  two  collections  and
         stores  the  result. modulus 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(), modulus<int>());
    
         After this call  to  transform,  vecResult(n)  contains  the
         remainder of vec1(n) divided by vec2(n).
    
    
    
    INTERFACE
         template <class T>
         struct modulus : binary_function<T, T, T> {
          T operator() (const T&, const T&) const;
         };
    
    
    
    WARNINGS
         If your compiler does not support default  template  parame-
         ters,  then you always need to supply the Allocator template
         argument. For instance, you need to write:
    
         vector<int, allocator<int> >
    
         instead of
    
         vector<int>
    
         If your compiler does not support namespaces,  then  you  do
         not need the using declaration for std.
