+- **Protected Float computed fields to always return valid numbers**
+  - Error: `TypeError: value.toFixed is not a function` in product list view
+  - Added explicit float() conversion in all Float computed methods
+  - Ensures computed fields never return False, None, or dict values
+  - This prevents JavaScript formatting errors in tree views with monetary columns
