title: Laravel input number allow double values
body: <p>I need allow double values. How I can do it? I need allow, doubles like this:</p>
  
  <pre><code>- 1,22
  - 0,01
  - 2,33
  </code></pre>
  
  <p>I can validate with <code>numeric</code>:</p>
  
  <pre><code>$request-&gt;validate(['from' =&gt; 'required|numeric']);
  </code></pre>
  
  <p>But then I can write <code>1,32223</code>, <code>22,3322</code> and others. I need allow only 2 number after comma.</p>
