This is not really an error. The answer is correct if you assume continuous compounding. Try evaluating 90000*EXP(6*.01) which equals 95565.2891891.

#6

Yes, we need to know what the display showed when you pressed "e" to initialize it.

There are several settings:

DE
DB
CE
CB

as well as settings for compounding periods and payment periods that may affect it.

I really, really doubt there is any new bug in the FI routine after all these years.
