Fixed decimals in Alteryx is a type of data formatting which allows you to specify how many decimals should be included in a numerical field.
Altering the fixed decimal settings can help you clean and manage your data. It lets you adjust all data in a particular field to the same number of decimal places.
For example, if you have a field containing both 1.21 and 4.855, setting the fixed decimal to two would round both numbers to 1.21 and 4.86, respectively.
Setting fixed decimals in Alteryx is a simple procedure. First, select the field containing the number you’d like to change. Then in the Properties panel, go to the Data Formatting section and select the Fixed Decimal option.
Finally, input the required number of decimal from the dropdown.
You can also use the fixed decimal convention in the formula tool to specify exact rounding of a calculation. For more information about using fixed decimals in Alteryx, you can check out this official guide: (link to guide)
