Function template is_decreasing

boost::algorithm::is_decreasing

Synopsis

// In header: <boost/algorithm/cxx11/is_sorted.hpp>


template<typename ForwardIterator> 
  BOOST_CXX14_CONSTEXPR bool 
  is_decreasing(ForwardIterator first, ForwardIterator last);

Description

	Note
	This function will return true for sequences that contain items that compare equal. If that is not what you intended, you should use is_strictly_decreasing instead.

Parameters:

`first`	The start of the sequence to be tested.
`last`	One past the end of the sequence

Returns:

true if the entire sequence is decreasing; i.e, each item is less than or equal to the previous one.
