Hello! I need in my printed invoice report column with untaxed price. My base tax is included in price, so [[ formatLang(l.price_unit) ]] returns me price with tax.

How can i display that what i need without interference with complicated python code and other complex things? :)

Math operations are permited in sxw?

Something like this is fair enought: [[ formatLang(l.price_subtotal) ]] / [[ formatLang(l.quantity) ]] = needed value

Thanks you in advance
