Hello,

I have the same problem in Odoo8 Qweb reporting.

Decimal Accuracy is set and it's working nicely if number in Qweb is defined as "t-field".

If you need to calculate or call function you need to do it with "t-esc" function and in that case number is not formatted correctly. As I saw, you can use "formalLang" but you have to wrap old RML parser with Qweb one as in "report_payslip".

But isn't this nonsense. We are throving away RML reporting in behalf of Qweb and now wrapping it again? What will happen in Odoo 9, will this solution work also (as I know there will be no support for RML)?

What can be done? Call a function and format a number on 'python' side ???

Thanks for any information or solution,

Matjaž

Hi Iming,

In order to change the digits you must go to Settings/Technical/Database Structure/Decimal Accuracy and here can change all the fields digits.

In order to change the decimal or thousand separator, you must go to Settings/Translations/Languages, select your language and change the values.

Hope this will help you!

Regards, 

Juan.
