JFormattedTextField

I have a JFrame with several JFormattedTextFields to get number input from the user. I use the following code to create my JFormattedTextField.

JFormattedTextField numberinput = new JFormattedTextField(NumberFormat.getInstance());

My first question is fairly simple: how do I get a number from my JFormattedTextField? I tried to do the following but always got a castException (when I changed the float to double it sometimes works, but I would like to asign the value to a floating point):

float input = (Float) numberinput.getValue();

The second question I have is a bit more difficult. I use a JSpinner with a numbermodel, so it actually also uses a JFormattedTextField to display my number values. I want to adjust this JFormattedTextField to always show 3 fraction digits. I use the following code to create my JSpinner:

SpinnerNumberModel model = new SpinnerNumberModel(1.000,1.000-0.501,1.000+0.501,0.001);
JSpinner spinnumbers = new JSpinner(model);

Thank you very much
