title: Angularjs: parenthetically show negative numbers?
body: <p>Is there a way to either:
  1) filter currency numbers without any indication of which currency the number is (including a dollar sign; no symbols what-so-ever)?
  2) filter regular numbers by showing negative numbers in parentheses?</p>
  
  <p>E.g. -12.345 filtered would look like: (12.345)</p>
  
  <p>Thank you.</p>
