PowerBI Report Builder - Number Formatting Issue (negative rounded zeroes)

I am stuck trying to format rounded zeroes in PowerBI Report Builder.

If the number rounds to zero but is less than zero then I want to show the zero in parenthesis, however I can't seem to do this.

ie; -0.1, formatted to 0 dp shows as 0, not (0)

I tried using standard formatting approach... #,##0;(#,##0);'-' I expected this to show (0) as per MS Excel.

I also experimented with using expressions but could not seem to get the desired outcome.

P.S: I have set font colour using an expression so I know the values are definitely below zero.

It's a bit untidy, but this should work..

Set the format expression to

=IIF(
    Fields!num.Value >=0, 
    "#,0;(#,0);""0""",
    "(#,0);(#,0)"
    )

Here's the result (in the last column)
