title: RegExp to parse currency value
body: <p>I would need to write a RegExp in AS3 which parses an Excel formatted currency value into a number:
  E.g.
      RegExp($35,600.00) = 35600</p>
  
  <p>And checks if it is correctly formatted (with the "," as the thousands separator, and the "." as the decimal point. The currency symbol could be any (not just $) and could stand at the beginning or the end.</p>
  
  <p>So I would just need to strip every non digit from the number and check if is valid.</p>
  
  <p>Thanks!
