I have a numeric choice type in my application.

$builder
        ->add('test', 'choice', array('choices' => array('1' => 1, '0.9' => 0.9));

The property test is of type float.

Since the Form component populates on every submit the property test with '0.9' (string)
but in the entity there was 0.9 (float) doctrine detects the change and updates the entity
even though this is not necessary.

What do you think about a option to the choice field to cast to integer or float? I see several
use cases where this makes sense and I think in a lot of applications such updates are executed
without any notice.
