I know we can use userinfo.CurrencyIsoCode to get currencycode for user in multi currency org. For single currency org we can manually look into company information and see currency locale. https://help.salesforce.com/articleView?id=admin_currency_set_locale.htm&type=5
But is there any way we can use apex to get currency code for single currency org's. I checked both organization and user object if there is any field for default currency but there is no field. Currencytype object is also not enabled in single currency org.
I need to know if there is any other salesforce object from where we can get this information. I don't want to create a custom object where admin can store this information.
