200LX, 17b, 19b - Solver Problem?

[Peter A. Gebhardt]

Quote:Is there a simple test case for said bug? If so, I can give it a quick test run on my 200LX. So far, I haven't run into any solver anomalies on it, but I haven't used it as extensively as Don and his 17BII, for example.

Sorry, no.

I'll try to construct one from the underlying formulas for the German accounting method for savings accounts, where the STAFF (Staffelzins) method originated from.

I'm also currently testing outside the calculator realm with another desktop program, which i use for assessment reports.

And also shall cross-check with my 17bII S/N: 3611M00944.

Best regards
Peter
