Android Question new dialogs library, how to output decimal number?

I see that in the new Dialogs library, the input spinners can be separated by a decimal point.

but how to you assign the decimal input (with spinners), to let's say a float, or double variable?

So, if I set a spinner number input to 28.35, how to get that assigned to a variable?

I'm very confused. Is the decimal number just cosmetic?

Appreciate the feedback.
