If you want to remove decimal in product you can do by set zero in decimal accuracy from Settings -> Technical -> Database Structure -> Decimal Accuracy

if you want to remove zero in total and subtotal you have to set decimal places in your currency by the some hack in database table res_currency, you have to change column decimal_places to zero.

Hi everyone! I am having a similar issue. Would it be possible to change this but on the Inventory and Manufacturing modules?
I work with products that will always be integers, but those two modules always show units as 5.00
I want it to be displayed as 5

From your answers above, I have tried changing the Settings -> Technical -> Database Structure -> Decimal Accuracy, and in particular the Product unit of measure to 0 decimals.
An error message appears saying "You are setting a Decimal Accuracy less precise than the UOMs".

Any ideas on how to change it?

Thank you a lot in advance! 

Hello Odooers,

I think if you are dealing with Monetary fields, then you dont need any code change, only need to set proper

"Decimal Places" in currency settings. Steps to change Subtotal fields (Monetary) decimal accuracy from 2 digit to 3 digits: 1. Activate Multi Currency from General Settings (Settings > General Settings > Accounting ('Invoicing' If Community)), Now activate Multi-Currencies from Currencies section. 2. Now go to Accounting ('Invoicing' If Community) > Configuration > Accounting > Currencies. 3. In currency form change value 0.010000 to 0.001000 in Rounding Factor field and save record. I hope this will helpful. -- Regards Haresh Kansara Odoo Application Engineer

Hi Vu,

The answer of Niyas is perfect once you will change the product price digits. for the subtotal and unit price go to the price list and Open the currency and change the rounding factor which will affect in unit and subtotal.

Thanks.

Hi,

To adjust the decimal points , activate the developer mode and navigate to Settings -> Technical -> Database Structure -> Decimal Accuracy.

Adjust the number of decimal point from here.
