title: How to define an input to save float in Easy admin?
body: <p>I'm on Symfony 4. I would save a decimal entry and Easy admin say "This value must be string", it generate a text input in the HTML.  </p>
  
  <p>I tried to not change the type and set the type to number too. I tried too to set the scale option to "force" the type but it continue to ask me a string... </p>
  
  <p>easy_admin.yaml</p>
  
  <pre><code>- { property: 'points', label: 'BO.label.points', type: 'number' }
  </code></pre>
  
  <p>Property of my entity</p>
  
  <pre class="lang-php prettyprint-override"><code>    /**
       * @var float|null
       * @ORM\Column(type="decimal", nullable=false, precision=12, scale=3, options={"default":0})
       * @Gedmo\Versioned
       */
      private $points;
  </code></pre>
  
  <p>I would to save my value. When I write 3, it's not okay because Easy Admin is waiting a pure string.</p>
  
  <p>EDIT : I added these options to my number type : </p>
  
  <pre><code>- { property: 'points', label: 'BO.label.points', type: 'number', type_options: { html5: true, input: 'number' }}
  </code></pre>
  
  <p>Anyway, Easy Admin always asks a string. Any idea ?</p>
  
  <p>Thank you for helping.</p>
