When I sum these fields in Alteryx (screenshot is from the source data):

My result is:

Does anyone know how these extra digits are making their way into my calculation? All of the numeric fields throughout the workflow, from the source input through the formula tools, are type Double. I have a Data Cleanse tool in my workflow before the formulas to change all nulls to 0 to prevent the nulls from throwing anything off.
Thanks,
John
