Numbers show as 0, 0.0, or 0.00 (0, 1 or 2 decimals), applying rounding, but the Tasks Timeline View Options do not have a setting for the Number Decimal Display.
How can I change the Number Decimal Display setting in Tasks Timeline view?
Clarity 16.2.3
Adjust the Number Decimal Display setting in the Grid View Options, and it will apply the setting for all three views (Timeline, Board, Grid).
