Answer 2

Prompt dialog is managed by system, I don't think there's any way web code can control what keys are allowed in the prompt input box. I guess your best bet would be to try to convert the input into number, and repeat asking for input while the input ia not a valid numeric expression.

Answer 3

Will I think it can be made easier. Assign "prompt" numerical value

Answer 4

Will. That's the decision I've come to.
