Truncate Trailing Zeros not respected in ListViews

Steps to reproduce:

1. Make sure your user's preferences are set "Truncate Trailing Zeros" = No.
2. In a Product change the Qty/Unit value to 1.50 and save it.
3. Refresh the page.
4. In Detailview, the value is displayed as 1.50
5. In Listview, the value is displayed as 1.5
6. Now set "Truncate Trailing Zeros" = Yes in your Preferences
7. Detailview now displays value as 1.5

Listviews should also respect this setting.
