)

else:

return amount

This is a custom code I have developed for purchase

It calculates the margin% for purchase and I have set a inverse method for margin so when ever I change the margin based on a Boolean(mrp_updateable) field it revere mrp or price_unit

But when I check this will results to some decimal point differences

If I change margin as 20 then when I save it shows 19.99 and if I change discount it changes price_unit

Can anyone review the code and help me

Thanks in advance..

Hello Mad Max ,

The issue you are facing with the slight decimal point differences when changing the margin and saving

could be due to several factors such as precision errors in floating-point arithmetic or how Odoo handles rounding.

Here are a few steps to ensure your calculations are as precise as possible:

1) Ensure Precision in Float Fields:

Make sure the fields involved in the calculations (like margin, mrp, price_unit, etc.) have the appropriate precision.

2) Use Rounding:

Explicitly round your values to avoid precision issues when performing arithmetic operations.

3) Refactor Calculation Logic:

Ensure your calculation logic is consistent and uses precise arithmetic.

Let's go through your code and make some adjustments to improve precision and clarity.

Thanks for the effort.
but no luck for me.

Add Import for float_round and float_compare:

from odoo.tools.float_utils import float_round, float_compare

Update _compute_margin to use float_round:

rec.margin = float_round(rec.margin, precision_digits=rec._get_digits('Product Price'))

Update _inverse_margin to use float_round:

rec.mrp = float_round(rec.mrp, precision_digits=rec._ge(price_unit, precision_digits=rec._get_digits('Product Price'))

Add Helper Method _get_digits to fetch precision:

def _get_digits(self, precision_name):
    """Get the number of digits for the given precision."""
    return self.env['decimal.precision'].precision_get(precision_name)
