The third expression for the PPMT function appears to be incorrect, containing too many parameters.

Current Expression:
=PPMT(3%;1;12;100;1;200;1)

Result:
-23.435558876±ε

I believe the corrected expression should be:
=PPMT(3%;1;12;100;200;1)

It's unclear if this affects the text of the function definition until a formula definition is added.
