Hi, I am a beginner in odoo development. I have added a new smart button inside the customer form to view its total unreconciled amount and redirect too its unreconciled entries, I have achieve getting its total value, however I don't know how to add thousand separator and set default decimal places. 

I don't know if there is an "odoo-way" in doing this or should i just convert it to String and then add an comma separator function before returning its value
