title: What to do when you need integers larger than 20 digits on mysql?
body: <p>Seems like <code>BIGINT</code> is the biggest integer available on MySQL, right?</p>
  
  <p>What to do when you need to store a BIGINT(80) for example?</p>
  
  <p>Why in some cases, like somewhere in the Twitter API docs, they recommend us to store these large integers as <code>varchar</code>?</p>
  
  <p>Which is the real reason behind the choice of using one type over another?</p>
