    I was a bit disappointed to learn that math-related Python packages don’t seem to have an ln function. They all use log for the natural log and also have a log10.

      Base e is considered the natural logarithm and is what you’ll get if you call log in most programming languages targeted at math.

        Why is that, off the top of my head I don’t remember seeing base e logarithms too often, why are they so important?

          They get used all over especially in differential equations.

          Log10 basically only comes up in statistics for doing a log plot in base 10.

          Basically high school math won’t use the natural log much, but once you hit university higher level math it becomes apparent it’s the one everyone actually uses regularly.

      You know what’s even more dissapointing? bc - arbitrary precision calculator for linux shell uses ‘l’ for natural log, just a single letter.
      And there’s no other log function, so when you need logx(y) you write: ''l(y)/l(x)".

          Yes? Suffer -> Suffering / Suffers ? Is this not correct?

      Make your own package, or just macro that shit.

      That’s because mathematicians use log for the natural logarithm. Log base 10 would be log_10

      “ln(x)” is another way of writing log sub e of x https://en.m.wikipedia.org/wiki/Natural_logarithm

      The “ln” of the “you son of a bitch. I’m ln” is referencing that identity

      ln(x) (I believe abbreviated from the french logarithme naturel) is the same as the logarithm of x base e (loge(y))

      Edit: subscript doesn’t seem to work for me on Jerboa but I’m keeping it as it is

        It’s also called logarithme népérien, for Jonh Napier, mathematician who discovered a lot of the properties of the logarithmic function.

          Pretty sure that superscript is using circumflex

              Huh you are right. It only works on the web frontend, not on the mobile apps.
