Yes, it is.
It is not possible to display the numbers affected by the bug correctly in DEC mode. It's not worth trying. Switch to FLOAT mode and add the corresponding 6×16^n. If only this could be automated somehow...
A small program that adds the required 6×16^n to the incorrect result that appears in FLOAT mode
