73 divided by 47 is not 1.55. It’s 1.5531914893617021276595744680851....
The problem you describe is a likely a function of the precision of the display or even of the calculator itself, not of the calculation. Calculators have a limit on precision as well as a limit on the display. Most all have enough precision to be irrelevant, but not always.
I looked around online a little. The new HP 15C is apparently still available, but quite a few reviews complain of the quality (early failures etc.)
I had a TI-58 programmable calculator in high school and college. It was fun to program, and cheaper and more portable than a PC. It went kaput when I couldn’t replace the rechargeable battery pack.
But now, I have a ‘58 emulator on my phone. If I ever need more than that, I have Excel and matlab/octave.
I miss the HP 33 engineering calculator. I have a really old one I need to get fixed, if that is even possible.
