If you have a Text field in a DataPage - submission form and you to use it for entering an currency, you can't formatting settings. While this field in the table does have the correct DataType.

If you have a form element 'Calculated Value', then is the formatting settings is available.

There is a workaround solution in an JavaScript but you make it quite complicated. I do believe that for something so simple, this must be standard functionality.

For using percentage is this more or less the same issue.
