(documentation average ChineseLanguage "这是一个部分函数,只要一个 List 的元素都是 RealNumber,它会把这个List 和一个 RealNumber 联系起来。和这个 List 联系的 RealNumber 等于这个 List 内的 RealNumber 的数学平均 除以列表元素的总数。") Merge.kif 5448-5450
(documentation average EnglishLanguage "A partial function that relates a List to a RealNumber, provided that the List only has list elements that are RealNumbers. The RealNumber associated with the List is equal to the mathematical average of the RealNumbers in the List divided by the total number of list elements.") Merge.kif 5443-5447
