    Is there a reason you want to use regex and not simple comparison like x < 100 && x > -100 ? – raphaelSeguin Dec 19 '18 at 10:51

You can use a regex range generator, such as http://gamon.webfactional.com/regexnumericrangegenerator/

I think this regular expression will do it:

/^-?([0-9]|[1-8][0-9]|9[0-9]|100)$/

use https://regex101.com/ for checking your regex.

and use (?:\b|-)([1-9]{1,2}[0]?|100)\b expression to print numbers from -100 to 100
