How to display currency on a number field?

I'm having trouble finding how to have a number field display as currency. I'm building a financial application and would like to have that.

It depends on how you would like the currency to be added. 

Could you please provide us more information on how your form works and what you expect it to output?

We do have a widget that allows you to set the currency and the thousands place separator, here's the widget: https://widgets.jotform.com/widget/masked_input 

Let us know if that will work.
