 NAME

   greater_equal	 - Binary function object that returns true if its
   first argument is greater than or equal to its second

 SYNOPSIS

   #include <functional>

   template <class T>
   struct greater_equal ; : binary_function<T, T, bool> {
    typedef typename binary_function<T, T, bool>::second_argument_type
 						 second_argument_type;
    typedef typename binary_function<T, T, bool>::first_argument_type
 						 first_argument_type;
    typedef typename binary_function<T, T, bool>::result_type
 						 result_type;
    bool	operator() (const T&, const T&)	const;
   };

 DESCRIPTION

   greater_equal	is a binary function object.  Its operator() returns
   true if x is greater than or equal to	y.  You	can pass a
   greater_equal object	to any algorithm	that requires a	binary
   function.  For example, the sort	algorithm	can accept a
   binary function as	an alternate comparison	object to sort a
   sequence.  greater_equal would	be used	in that	algorithm in
   the following manner:

   vector<int> vec1;
   sort(vec1.begin(), vec1.end(),greater_equal<int>());

   After	this call to sort, vec1	will be	sorted in descending order.

 WARNINGS

   If your compiler does	not support default template parameters, then
   you need to always supply	the Allocator template argument.  For
   instance, you'll have to write :

   vector<int, allocator<int> >

   instead of

   vector<int>
