I would recommend looking at the Internationalization configuration as the first step to ensure that it is set to the right option to suit your locale and currency formats. You can check https://community.denodo.com/docs/html/browse/7.0/vdp/vql/advanced_characteristics/creating_new_internationalization_configurations/creating_new_internationalization_configurations for more information.
Denodo provides a variety of functions that can be used to perform mathematical and string operations as well as conversions. You should be able to handle this by changing the value of field expression in the output tab, once you edit your view. You could also create custom functions to return converted values. You should perform these conversions explicitly in Denodo, to apply the conversions you want in each case.
Hope this helps!
