Rounds off $a which can be either an array-accessible value (Iterator+ArrayAccess || array) or a raw numeric value.

  • Tag usage example

    <v:math.round a="[mixed]" fail="1" decimals="123">
    	<!-- tag content - may be ignored! -->
  • Inline usage example

    {v:math.round(a: [mixed], fail: 1, decimals: 123)}

If TRUE, throws an Exception if argument "a" is not specified and no child content or inline argument is found. Usually okay to use a NULL value (as integer zero).
