A series to test.

A series or array where each element is 1 where the input series or array is not inf or nan and 0 where the input series or array is inf or nan.

a = {1, 2, inf, nan};

b = 5;

c = {};

finite(a) == {1, 1, 0, 0}

finite(b) == {1}

finite(c) == {}

FINITE always returns a series.

FINITE returns an empty series if the input is an empty series.
