title: Change currency format to show 4 decimal places instead of 2 globally
body: <p>I have a working website, where I use this expression everywhere.</p>
  
  <pre><code>price.ToString("C")
  </code></pre>
  
  <p>It currently shows 2 decimal places, eg. $1.45</p>
  
  <p>Now I need the website to show 4 decimal places, eg. $1.4515</p>
  
  <p>Is there any easy way to change it globally?</p>
