title: How can I get the precision of a decimal in js?
body: <p>This is probably a super easy thing to solve, but I just can't think of an elegant solution right now.</p>
  
  <p>Given the following numbers, how do I find the precision (.0001) of each number. </p>
  
  <pre><code>126.01
  1.3450
  </code></pre>
  
  <p>Update:
  The number of digits after the decimal. </p>
  
  <p>The output from the top two numbers would be.</p>
  
  <pre><code>.01
  .0001
  </code></pre>
