#binary_search_raw(target, opts = {}) ⇒ Object

binary_search_raw param1: should be comparable against elements in the array if not, provide a block which can be used to do equals returns the index with the target if possible, but will otherwise return the index of the element that is the smallest element larger than the target. It’s raw because it does not check if the array is sorted or not

		return p_bisearch_internal( 0, count-1, target, right_flag) do |a,b|
			yield a,b
