Need more Decimals - What If scenario

I would like to create a what if scenario with the following input:

Data type - decimal number
Minimum number - 0.00000000001
Maximum number - 0.000001
Increment - 0.000000001
Default: 0

However with these numbers I am not able to create the parameter, because it’s not possible to click on the ‘ok’ button.

When I try to create the formula manually I receive the following error:

GenereateSeries Function cannot have a floating point IncrementValues less than 1E-6.

Is there an option to bypassthis error?

Thank you.

Hi @Folkert,

Welcome to the Forum!

Have you tried creating this list in Power Query using List.Generate?
Here’s a link to the documentation.

M code example:

    MinNum = 0.00000000001,
    MaxNum = 0.000001,
    Increment = 0.000000001,
    Source = List.Generate( ()=>MinNum, each _ <= MaxNum, each _ + Increment ),
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Changed Type" = Table.TransformColumnTypes(#"Converted to Table",{{"Column1", type number}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"Column1", "myNumber"}})
    #"Renamed Columns"

I hope this is helpful, here’s my sample file

Hi @Melissa

Works like a charm, cheers!

Just one more question. How do I turn from this to a slicer with a single value?
Somehow the option ‘single value’ is missing.


Versus (what it should be)



As for the slicers see the documentation here, in this article:

@Folkert, @Melissa,

The single value slicer is an extremely rare bird, hardly ever seen in the wild. The only way I’ve ever gotten that option to appear is from a calculated column generated from a parameter using the GENERATESERIES() function.

If anyone has another way to access this option, I’d love to know it.

Yes, I second that. Would love to find a way to access that…

@BrianJ @Melissa

Thanks for the heads up, although the message is quite disappointing to be honest :stuck_out_tongue: Hopefully Microsoft will focus on the reproduction of this rare bird in the near future. Anyway I will start doing some trial and error and see if I can find a solution.
