Changing numbers to % format

8 - Asteroid



I have a few columns with numeric data. Data type is Double.


My goal is to change the data format to %. 


I used the Multi-Field Formula to multiply data by 100.


How do I add "%" to those fields?

Hi @cwoo


To show the percentage sign you'll have to store your number as string. In that case you can change the data type in your multi field formula to string. Bundle your current formula in a tostring(....) and add a +'%'. 


Hope that works!

Unfortunately, there isn't a way to add a  percentage sign AND keep them as a numeric field. If they don't need to be numeric, you can change the fields to a string and manually add the '%'.  You can do all of that with the same Multi-Field Formula tool:

If you want to be able to use the field for calculations in formulas you will need to divide the field by 100 to get it into a decimal form by using the formula field.


If you want to add the actual '%' you will need to convert the field to a string format and then use the formula field to add the % sign, but then you will be unable to use in it mathematical formulas.

Hi @danrh


So I did that but I am seeing an error message. Please see below. 


Do I have to change the original fields data type to something? It is currently Double.

I would use the select tool that you have there to change the data type to a string and then just use the formula tool to set the field equal to itself  + ' %'.

I believe the error is occurring because it hasn't changed it to a string before you are adding the %

I didn't change output type to String - thus the issue.
