Calculators are Calculators are technology. What is the advantage

I love RPN, and I liked it so much the first week i got a 50g that I wrote an RPN calculator implementation.

I thought the 50g had RPN built in?

>>56524017
Yes it does.
I couldn't find a nice enough desktop RPN calculator so I wrote one.

It's very fast to use.
You can rearrange the calculation in the middle, by swapping or rolling the stack. If you notice you missed something (e.g. forgot to square) you can often swap, square, swap, and keep on.

RPN and RPL calcs are super easy to program too. Much easier than anything else.

The HP-28/48 series, which includes the 50G, are slightly different than classic RPN calculators. They use a language that's pretty similar to Forth called RPL instead. However, the ease of programming largely remains.

Both use postfix notation, where you enter your value(s) and then hit a key that executes an operation on the data in the stack.

Here's a really autistic and good site about HP RPN calculators:

http://www.hpmuseum.org

It's focused on the RPN calcs, if you want to learn about RPL calcs:

Both sites are really useful. If you're an HP-41 or 42s nerd there's this site too:
