My HP 10bII+ is much faster than HP 12c!

[SteveC]

I found this thread trying to verify if the HP 10Bii+ solves the two or more sign
change cash flow IRR problem. Simply answering 3.652% to the cf0 +1000,
cf 1-29 -1000, cf30 +49,000, is inferior and misleading as it makes no hint that
there may be more to the answer.

One more point in favor of the Gold Standard 12C that I trust.
The "Error 3" telling me there are multiple solutions is the best solution.
My 17B from 1989 also get the right answer of 3.652 & 100 after asking for
seeds and then running pretty quickly.

A Quick wrong or misleading answer is not at all superior to a slightly delayed
correct answer. The 12C Platinum runs this example quickly.

NPV does not have these problems.
