How many decimal places can I use in a what-if parameter?

Hi all,


I am trying to create a paramter to hold a currency exchange rate. I need this value to be shown and editable in 4 decimal places.

I am using this formula = GENERATESERIES(0, 1, 0.000001and have stored my value as data type decimal number and format currency with 6 decimal places. However if I try enter 0.0004 the value automatically changes to 0.  Also the information icon pops up on the slicer with the message 'Showing representative sample'.


How can I acheieve this as I need at least 4 decimal places for accuracy.

Hi @HarrisonBi ,


You need to change the type from whole number to decimal number and then adjust its digits. The reference is as follows.


For more details, you can refer to below document:

Use what-if parameters to visualize variables - Power BI | Microsoft Docs

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Hi Henry,


This doesn't resolve the issue I am facing. It doesn't allow me to enter values, I need up to 6 decimal places of accuracy.  See attached images.
