Dollar functions returns $N/A for the value having more than 10 digits

What is the type for the variable where you store the value entered in the text field? Integers in Appian are limited to 2,147,483,647, so if you enter a value higher than that number, it will display $N/A in your text field. However, if your variable is defined using a decimal or text, it should display correctly with the dollar function.

Hi Peter, I tried that , the value is coming as

Can you confirm the type of the variable you stored the number value in?

Can you confirm the type of the variable you stored the number value in?

a!textField(
                    label: "Revenue at risk (US$)",
                    labelPosition: "ABOVE",
                    value: if(
                      rule!GLB_isBlank(
                        index(
                          ri!PF_Request,
                          "RevenueAtRisk",
                          null
                        )
                      ),
                      null,
                      fn!dollar()&
                        index(
                          ri!PF_Request,
                          "RevenueAtRisk",
                          null
                        ),

this is the code I have written, please let me know what is the mistake

I tried Text Field, Integer Field, Floating Field, Fixed, Text and Dollar()@"9999999999999999" is also not working

I don't personally recommend using the code "fn!dollar() & index( etc...", as this won't actually call the dollar function on the value you're trying to convert (it will just insert a dollar sign, which can be done more easily just typing "$"). 

To recap, the correct syntax for dollar() is:

dollar(
  (value),
  (number of decimals) [optional],
  (exclude commas) [optional]
)

This example code (14 9's, or 99 trillion) works fine - once you add more 9's, the number starts behaing weirdly no matter what you do.

dollar(
  "99999999999999",
  2
)
