Help would be appreciated. I cannot make a chain of if-else statements equal to the cases formalism. What am I missing. I have tried the less than or equal only in the cases formalism. That didn't work either. The if-else results are correct, the cases formalism is not correct.

Oops sorry. I had errors in my formulas. Here is the corrected version where the two formalisms do agree.

No problem, when possible, better ask.

I would point out that currently you can avoid the nested if/else and convert it in if/else if/else (if you wish), simply adding more arguments. As side note if you delete an argument from the default if/else, you'll get an if without else.

Also, since the topic is about if/else vs cases, I would like to highlight that cases has a different coding approach to evaluate in some situations where if/else is not allowed to; this feature comes at the cost that you shouldn't make assignments ( : ) inside its arguments, while in if/else you can safely build block of codes inside it using the line function (see here and here for examples).

Davide,
Thanks much. Very helpful as always.
