Negative and Positive number

[sfmendes91]

Is there a way of using maska for both negative and positive number?

For example:
-99.10
or
99.10
should be a valid value.

Unfortunately I didn't found anything in the documentation.

Have you found a way?
For me, the:

            data-maska="m0.99"
            data-maska-tokens="m:-:optional|0:\d:multiple|9:\d:optional" 

works, but is there a better way?
