When Alteryx 2018.4.3.54046 reads an xlsx, it can "introduce" a float where there was none before. This only happens in a specific situation and it's not clear WHY it is doing this. The actual numbers are exact to 2 and 3 decimal places in Excel. It isn't a matter of formatting or display. That's what they are. An example number: 1.43.
If there is a string value in the same column, then Alteryx will read the entire column as a string. So far, so good. When it does this, some of the numbers now look like floats. 1.43 now looks like 1.42999999998 in Alteryx. Not all of the numbers get this weird float treatment.
I cannot control the source files and they may have strings in various cells of the "numeric" fields. I have to read everything as strings. I want to know why this happens and what to do about it. Thank you.
