What do you keep on your 42S?

[Trond]

Very little. I am a relatively "casual user" compared to many here. I just like doing some quick calculations on my HP calculators. Unit conversions are the most frequent programs. I have a simple thing estimating the weight of whales based on their length. I also keep some random number generators: I frequently make multiple choice tests for students so I like to quickly create random numbers 1-4, 1-5, or 1-6 (sometimes these are also used as dice for games) so those are also some short and easy programs.
