title: Getting float/double from NumberPicker
body: <p>I am trying the <a href="https://github.com/SimonVT/android-numberpicker" rel="nofollow">https://github.com/SimonVT/android-numberpicker</a> library and the reference is <a href="https://developer.android.com/reference/android/widget/NumberPicker.html#getValue%28%29" rel="nofollow">https://developer.android.com/reference/android/widget/NumberPicker.html#getValue%28%29</a>
  Now both, the API level 11 NumberPicker returns int value in getValue method and also the SimonVT numberpicker returns int value.</p>
  
  <p>But I had set double values in the number picker by using following code:</p>
  
  <pre><code>String[] nums = {"1","1.5","2","2.5","3","3.5","4","4.5","5","5.5","6","6.5","7","7.5","8","8.5","9"};
  
  final NumberPicker listeningScorenp = (NumberPicker) findViewById(R.id.listeningScore);
  listeningScorenp.setMaxValue(nums.length-1);
  listeningScorenp.setMinValue(0);
  listeningScorenp.setWrapSelectorWheel(false);
  listeningScorenp.setDisplayedValues(nums);
  </code></pre>
  
  <p>Now I am stuck with how to retrieve the float/double values from NUmberPicker.</p>
