When I add items in a project the cents should round to two digits. Please see attached.
We've just updated the system so the calculations will always be rounded to 2 decimals, even where the data is being entered. Pricing was always shown as currency 2 decimals but now it will also show when calculating the values.
The extra decimal points are just when the calculation links are used (i.e. for Client Price or Markup), on the Add Item page. Once the item is saved the currency values display normally with 2 decimal symbols.
The 3 or 4 decimal symbols you'll occasionally see when the calculation is made is the actual value but once saved, as currency it will always show 2 decimals on anything but an Item Edit page (for example, the list pages).
