Parameter issue

Hi brankocareer,

Thank you for reaching out to Microsoft Fabric Community.

The issue occurs because power bi numeric input slicer applies internal optimizations when handling large numeric ranges generated by GENERATESERIES. That is why there are unexpected rounding errors where even numbers display incorrectly.

• Use the dropdown slicer instead of numeric input slicer, this will pick the exact values instead of applying internal optimizations.
• Create a custom DAX table, this prevents the slicer optimizations that effect numeric input fields. Use the Value column in the slicer.
  Ex: Budget Parameter Salaries Table = ADDCOLUMNS(GENERATESERIES(-1000, 1000, 1), "Value", [Value])
• Power BI slicers sometimes handle numbers as floating-point values internally, causing rounding errors. please use the following DAX command if required
  Budget Parameter Salaries = INT(GENERATESERIES(-1000, 1000, 1))
