Here is the right answer to your question.
Be careful, your interval finishes with 0 as beyond they are positive...and you're looking for a negative.
Here are included all numbers between -5 and 0 (included -5)
Notice that you can get infinitely close to a number without reaching it. How?
-4.99999...999...(and you'll never reach -5. In this case we do though)
-0.00000...000...1 (and you can spend the rest of your life placing zeros in between and never reach to 0)
