Inventory costs are calculated and reported at a level of decimal precision that is based on the format for the chosen currency.
The level of decimal precision indicated in the Format field of a currency record is used for inventory costing calculations and cannot be changed. This maintains consistency between inventory costing and reporting.
For example, if you have selected USD (United States Dollar) as the currency for an item on the item record and the format is USD, then the decimal precision for that item's costing and reporting is two decimal places.
Standard Costing is an exception. Standard Costing calculations are performed with decimal precision to seven places. For example, 9.87654321 is calculated as 9.8765432. For details about Standard Costing, read Standard Costing.
