Create Category from numeric field

Hello! I'm trying to create a simple categry with the next logic, but I don't see the category "0%" and I don't know how to make ir appear. For devices with this field = 0.00 shows me the next category ">0 -25%".
This is a Custom Column in Power BI, no Power Query, and I'm using DirectQuery:

%_Range_Column =
SWITCH (
    TRUE(),
data_device[%_days_with_traffic] = 0.00, "0%",
data_device[%_days_with_traffic] <= 0.25, ">0 -25%",
data_device[%_days_with_traffic] <= 0.5, ">25 -50%",
data_device[%_days_with_traffic] <= 0.75, ">50 -75%",
data_device[%_days_with_traffic] > 0.75, ">75-100%",
"0%" )
A sample of my data is:
Device_ID%_days_with_traffic%_Range_Column
A0.00>0 -25%
B0.26> 25-50%
C0.502> 50 -75%

    adriancho_BI Could be a decimal precision issue. Try this:

    %_Range_Column =
    SWITCH (
        TRUE(),
    data_device[%_days_with_traffic] < 0.001, "0%",
    data_device[%_days_with_traffic] <= 0.25, ">0 -25%",
    data_device[%_days_with_traffic] <= 0.5, ">25 -50%",
    data_device[%_days_with_traffic] <= 0.75, ">50 -75%",
    data_device[%_days_with_traffic] > 0.75, ">75-100%",
    "0%" )

      Thanks for the answer! But I've already tried that approach without any change 😞

    Hi adriancho_BI ,

    Given the logic you've shared, your function syntax appears correct for the intended categorization.
    Sometimes, due to the way floating-point numbers are represented, a value that appears as might not be exactly zero. Consider adding a small tolerance in your comparison to catch these cases, such as the method Greg provided.
    Finally, please try changing the data type of [%_days_with_traffic] to Fixed decimal number.
