So, I went into Warehouse->Configuration->Units of Measure because I need boxes that contain 10, 12, 20, 25, 50, 65, and 100 units.
All of these worked correctly except for the box of 65.
When I try to create a new UoM I name it Box of 65 , chose Unit as its category, selected Bigger than the referenced bla bla, and then when I select the ratio as 65, when I save it the ratio immediately changes to 64.999999998375. Now, this wouldn´t be a problem by itself but when I try to export the OuM specifically uom_po_id/id instead of giving me the value for this UoM it gives me "product.product_uom_unit" which I believe is the model but that is not something I can use to import information back into the DB.
Does anyone have any idea why this is happening and how to make it work, is it because the number is odd?
