title: Get last number in string using javascript regex
body: <p>I've got the following String <code>"$120 foo $100 bar"</code> and I want to get just the last number so I end up with just "100".</p>
  
  <p>I've had an attempt at it but can only get the first number (120) instead of the second number. This is what I have so far.</p>
  
  <pre><code>price.value.match(/\d+/);
  </code></pre>
  
  <p>Worth noting, on some occasions I may just have one number in the String <code>"£80 GBP"</code>. I would like the regex to always give me the last number displayed.</p>
  
  <p>Can anyone suggest the regex I should be using?</p>
