title: Possible to use pipe formatter of Angular inside textbox control while editing?
body: <p>I've declared a format for splitting large numbers in groups of three digits and use it frequently like this.</p>
  
  <pre><code>&lt;div&gt;Huge number: {{ i_am_huge | make_threesome }}&lt;/div&gt;
  </code></pre>
  
  <p>Now, there's a request for corresponding functionality but implemented in an input control like this one.</p>
  
  <pre><code>&lt;input id="numeroUno"
         type="text"&gt;
  </code></pre>
  
  <p>The approach I can think of is to listen to typing and for each key perform a reformatting of the contents of the box like so.</p>
  
  <pre><code>&lt;input id="numeroUno"
         type="text"
         (keyup)="formatify"&gt;
  </code></pre>
  
  <p>However, while this approach would work, I can't stop wondering if it's too much of Q&amp;D, so before I build a whole control fauna around this paradigm, I'd like to get more info.</p>
  
  <p>The usual googling didn't give me much. However, give a rather unusual nature of the requirement, it might be hard to find.</p>
  
  <p>The assumption at this point is that input control isn't supposed to be used that way, which explains the clunkyness of my approach.</p>
