Just playing around, my MK-61, after a slight pause gives 7.9999993.
Doing [2] [ENTER] [ln] [3] [x] [e^x] also gives 7.9999993.

Interesting. Without guard digits it should be 7.9999973. What are the intermediate results you get for ln 2 and 3x this?

[2] [ln] = 6.9314717 E-01
[3] [x] = 2.0794415
[e^x] b = 7.9999993

Why do you add an [ENTER] before the log? It's classic RPN. ;-)

Because I'm an idiot! ;-)
