Hi, In Odoo 19, float precision is handled directly through the digits attribute on fields, not via dp.get_precision().
The fix is to remove the decimal_precision import and define the precision as digits="Product Unit of Measure" on the field. This is an expected breaking change during migration to Odoo 19.
Try the code below.
product_uom_qty = fields.Float(     string="Ordered Quantity",     digits="Product Unit of Measure" )
Hope it helps
