\(5.9639×10^{91}\) in a DM15L after 50''.

My DM15L was running at 48 MHz. If switched to 12 MHz it takes around 3 minutes.

I just tried again, and again my DM15L ran for 10 minutes with no result.

Then it occurred to me that I was running in FIX 2 mode, which could be affecting behavior. So I changed display mode to SCI 4, and I then got the same result in about the same time as your results.

Though it is specifically discussed, the manual is not completely clear (to me) about how display mode affects results, but it seems to have a dramatic impact. I would expect a setting with 2 digits of accuracy (FIX 2) would have finished faster than with 4 (SCI 4) since even when set to FIX mode, it switches to SCI mode as needed if the magnitude under/overflows.

Perhaps some of the other error and/or endless calculating errors reported above were also affected by the same issue. Try again using SCI 4 mode.

Thanks for the correction emece67; it motivated me to explore this further and learn a bit in the process.
