title: Laravel Form: Specify that the value is an integer
body: <p>Probably a really easy-to-solve problem but I can't find the answer.</p>
  
  <p>The form is a dropdown that shows a specific text for the user (Less than 100... etc) but generates an integer after submission (99, 199 or 1999). Right the result of the submit is as a string.</p>
  
  <pre><code>    {{ Form::label('people','Nb of people')}}
      {{ Form::select('people', [
              '99' =&gt; 'Less than 100',
              '199' =&gt; 'Between 100 and 200',
              '1999' =&gt; 'More than 2000'])
      }}
  </code></pre>
  
  <p>EDIT (following itachi's comment):
  The visitor needs to select one of these 3 options 'Less than 100' or 'Between 100 and 200' or 'More than 200'. Then the submission needs to send back an integer (easier to play with instead of a string) through GET method. The GET method part is working well but the issue is that the result is a STRING instead of an INTEGER.</p>
