That is authentic HP-25 behavior. I don't even have to get mine out of its drawer to check, I remember noticing this quirk back in 1977 and being annoyed at having to waste a line by adding an ENTER in that situation.

Consequently the infamous 3201 example has only 6 (!) correct digits (after rounding).

Indeed, but I came to the HP-25 from the Sinclair Scientific, which, to me, made the 25 the epitome of speed and accuracy. :-)
