js regexp floating number with leading zero

I need to make an input mask that meets the following requirements:

1. 1255454 - ok

2. 1.54546 - ok

3. 1,0056 - ok

4. 0.6565 - ok

5. 0,0056 - ok

6. 056565 - not ok

7. ds5asd - not ok

8. .0565656 - not ok

so far I have found this solution: "/^-?\d*[.,]?\d*$/.test(value)" but it doesn't cover these cases: ".0565656" and "056565"
