title: Angular currency pipe for -0 value
body: <p>I am using Angular currency pipe to show the amount with currency code transformed according to the locale. It is working as expected. Only in the case of -0 amount it is removing the -ve sign after transforming the amount. Is there a way to show the -0 amount according to a locale with a -ve sign?</p>
  <p>Example,
  For -0 in en-GB locale -
  The actual output is EUR 0.00
  The expected output is EUR -0.00</p>
