Hi,
1. Define Fields with Precision.
Use fields.Float for general decimal numbers, specifying precision with the digits attribute (e.g., digits=(16, 2) for 2 decimal places, or digits='Product Price' for named precision).
Use fields.Monetary for currency amounts, which automatically uses the precision of the associated currency_id field.
2.Perform Calculations Safely:
Odoo's ORM generally handles underlying decimal.Decimal objects for precision.
For explicit rounding in Python code, use odoo.tools.float_round(value, precision_digits=X) to ensure consistent rounding behavior.
3.Display Decimals in Views and Reports:
XML views and QWeb reports automatically apply the precision defined on the field.
Use widget="monetary" in XML for monetary fields to ensure proper currency formatting and decimal display.
In QWeb, t-field with t-options='{"widget": "monetary", "display_currency": record.currency_id}' or t-options='{"widget": "float", "precision": X}' can be used for precise display.
Hope it helps.
