在Erlang中，任何术语都可以与任何其他术语进行比较。Erlang术语比较的顺序为：

number < atom < reference < fun < port < pid < tuple < map < nil < list < bit string

因此nil〉0为true有关期限比较的更多信息

Yes, in Erlang, nil > 0 evaluates to true. But when Erlang programmer talks about "nil", he means the empty list: [] . If you write nil in Erlang code, it's just an atom 'nil' , like 'dog' or 'hello' . And any atom is larger than any number because of the following built-in hierarchy:

number < atom < reference < fun < port < pid < tuple < map < nil < list < bit string

But it's very important to note that "nil" in this line refers to empty list [] , not to the atom 'nil' .
As a side note: Evaluating [] > 0 also returns true because any number is smaller than nil.
And finally, [] > nil also returns true because nil ( [] ) is larger than any atom ( 'nil' ).
