@zojize I’m trying to achieve a similar effect in useSum packages/math/useSum/index.test.ts

test('reactive list', () => {
  const list = reactive([10, 20])

  const sum = useSum(list)
  expect(sum.value).toBe(30)

  list[0] = 21
  expect(sum.value).toBe(41)

  list.push(5)
  expect(sum.value).toBe(46)
})

Is Infinity a special edge case, and if so, can it be recognized and handled specially?
