Accurate Bernoulli numbers on the 41C, or "how close can you get"?

There's most probably no information available concerning this question. Thus there is much to do. I suggest to use the trace which is available in Nonpareil to figure out the 13-digit internal results of the operations you are interested in. You probably have some corner cases already in mind such as cos(x) close to \(\frac{\pi}{2}\) or ln(x) close to 1. Or maybe the SDK41 provides a decent debugger? Let me know if you need detailed instructions. IIRC Nonpareil doesn't support tracing out of the box. You have to compile it setting the option has_debugger_gui.
