Hi there, JAM3guitar. I appreciate your input from every angle.

I've replicated this issue in my sample QuickBooks Online (QBO) account, and it seems to have worked. Since it appears that my actual percentage of Change is 9.4519% in which on my report, it is showing 9.45% on the CHANGE column. 

To investigate why this behaviour is happening on your report, I advise contacting our Customer Care Team. Checking the root cause of this requires tools, like screen sharing, that only them has. They can also create an investigation ticket if other customers are experiencing the same thing. Ensure to review their support hours so, you'll know when agents are available.

As for your other concern in changing the number of decimal places to zero, right now it's unavailable. Since the decimal point is set as default in the program. I know how the feature you're looking for would be beneficial to your business. While we continue to make your experience with us even better, I recommend visiting our QuickBooks Blog to get the recent news, information about the latest features, and updates in QBO.

If you have specific questions please let me know. I will be more than happy to further assist you. Have a nice day.
