Add an extra decimal to a currency value

Hi everyone

I have a SharePoint column which is created as currency with two decimal places.

When I use this column in a Nintex Workflow Cloud workflow, the value returned only has one decimal place instead of two. 

How do I add another decimal to the number.

Example: “Cost” created as currency in SharePoint Online

The output of “Cost” should look something like R200.00, but in e-mails from Nintex the output from “Cost” is R200.0. How do I add the extra zero so that is displays with two decimal places?

Thanks
