Response format restrictions

Hello,

I wanted to know if it would be possible to add a formatting constraint on a user's response.

Example:

The question is: How tall are you?

For the response I would like to set 2 restrictions:

1.   Only type numbers, not letters.
2.   Include a restriction on the number of characters that can be typed, in this case a maximum of 3 numbers for example.

We would like to know if it is possible to make one or both points described above.
