In the post linked here https://travellingwiththyself.design/2019/02/11/exactly-between-zero-and-one/ I had asked a question-What comes exactly between zero and one?
Have you thought of the answer? It’s very simple.
In arithmetic, the number line starts from zero extends towards the negative integers and as well as towards the positive integers.
The answer to the question is 0.01 to 0.99.
Hope you have liked my answer.
