title: Shorten long numbers to K/M/B?
body: <p>I've googled this a lot but i can't find any helpful functions based on my queries.</p>
  <p>What i want is:</p>
  <pre><code>100 -&gt; 100
  1000 -&gt; 1,000
  142840 -&gt; 142,840
  </code></pre>
  <p>BUT</p>
  <pre><code>2023150 -&gt; 2.023M ( i still want 3 additional numbers for more accuracy )
  5430120215 -&gt; 5.430B
  </code></pre>
  <p>I would totally appreciate any custom functions to dynamically choose the limit if possible.</p>
