Getting product price in application level defined currency

I am following this example, and as shown I want to get price of product on ISML using following piece of code (ProductBOPricingExtensionImpl contains method that accepts only price type and currency):

ProductBO:Extension("Pricing"):Price("SalePrice",{currency_here})

Problem is, I don't know how to acquire any currency object to put in there, and the best way it would be to somehow get default/fallback currency defined on application level.

Solution

You can print out the price using this module. Also shows how you get the currency

<isinclude template="modules/Modules">
...
<ISProductPrice 
            ProductBO="#ProductBO#"
            Currency="#CurrentRequest:Currency#"
            ShowInformationalPrice="true"
        >

checkout the documentation in app_sf_responsive/staticfiles/cartridge/templates/default/modules/product/Modules.isml

It takes different scenarios into account, like if the customer is login and is eligible for a discount.
