I'm using IDR, and local rule stated the tax should be rounded down to whole number no decimal. I understand the tax rounding is to create least available cash denomination, but this is not what I'm looking for. i.e. for 10% tax of 88, it should be 8, not 8.8.

Can this be achieved in odoo 12?

This need to be applied both on sales and purchase.

thanks in advance.
