..float value..

Immediately suggests a JSpinner with an appropriate SpinnerNumberModel to me. E.G.

import javax.swing.*;

public class FloatSpinner {

    public static void main(String[] args) {
        Runnable r = new Runnable() {
            @Override
            public void run() {
                SpinnerNumberModel floatModel = new SpinnerNumberModel(
                        2.14f, 0f, 3f, .01f);
                JSpinner spinner = new JSpinner(floatModel);
                JOptionPane.showMessageDialog(null, spinner);
                System.out.println(
                        "User Chose: " + floatModel.getNumber().floatValue());
            }
        };
        SwingUtilities.invokeLater(r);
    }
}
