How come plus, minus, muliple and division regex operators also match decimal? : <p>I tried regex 'minus', 'plus', 'multiplication' and 'division', /[*+-/]/. This regex matches all the operator signs, but it also matches decimal point. How come? How to match only these operators but not decimal? </p>
