title: Removing commas in the standard return value of toLocaleString
body: <p>I've searched the web and I only found how to add commas between number, but I want to do a reverse which is removing the commas in number.</p>
  
  <p>Here is my JavaScript Code</p>
  
  <pre><code>const format = (num, decimals) =&gt; num.toLocaleString('en-US', {
      minimumFractionDigits: 2,      
      maximumFractionDigits: 2,
  });
  
  console.log(format(3460));
  </code></pre>
  
  <p>It returns, 3,460.00. I want it to return 3460.00 only.</p>
