Wolfram Alpha says that the result shall be
-7.497258185325587112905071831891248663417267943785263161571223470151837884956238​9571281869682281839570540842373435... × 10^6

So the 34s could achieve 26 digits.

Internally, this is computed using 39 digits so thirteen digits are wrong. Converting back to 34 digit double precision numbers isn't introducing more than a rounding error in the 34th digit which is already incorrect.

It wouldn't go to Walter's head. I wrote the vast majority of the mathematical functions

Paul, this is definitely an achievement, the 34s is an amazing tool, I use it on a regular base. I started some little programming on it recently and I love it.
Not sure I ever formally spent time to thank the team for that, not forgetting Marcus who also actively and very kindly helped me to flash it.

Note: Oh and BTW Paul, wish list item: I prefer complex numbers on the 15C with a dual stack ;-) ... for next time, may be on the 43s iteration?
