Excel: Excel is forcing percentages to 15+ decimals long after I removed any and all references to e and LN

I will try anything at this point (except precision as displayed). Custom formats do not work. I have deleted every custom format and then highlight the entire workbook, every cell in every sheet and forced every number four decimals. As soon as i change a number and run manual calculation boom 15+ decimals. Excel does not seem to care (putting aside the obvious that it is simply not practical or rational to "display" 15 decimals. I have removed all references and formulas to e and LN many many versions ago. Does not matter. What can I do?
