Sorry Michael i have been away from this site for a while....I lost something?

Long and sometimes heated discussions about how DM42 isn't GPL-compliant.
I'd recommend starting with this thread: https://forum.swissmicros.com/viewtopic.php?f=15&t=1866

Back on topic:

My calculating needs are taken care of by Free42, and when that's not sufficient, I reach for the big guns of Wolfram Alpha or Mathematica. Or I write programs in C or Java.

On the rare occasions I do still reach for a physical calculator, I use my HP-42S the most, followed by my HP-67 and HP-25.
