Talk:Null function

Null function can also refer to the null function in mathematics, there is a need to indicate that the null function here is related to computer science in the title of this article; the title should be "ull function (computer science)" the same as the article "Null(computer science)".

not serious

The article has contradictions. First it is said that the zero function is a subroutine, then it is said that it "is a (computer) function", defined on the set of states, that leaves all of these unchanged. But a computer function does not have as arguments the set of states, but input values, and the result ("image") of the computer function is also not a state. In any case, it cannot be both, a subroutine and a function defined on the set of states. — MFH:Talk 00:55, 20 January 2023 (UTC)
