but does it do RPN? As someone who survived engineering school with a hp32s I sometimes miss the rpn entry notation. That calculator could do integration which was awesome. (RPN was an entry system that used a stack. you pushed the number on the stack with enter, so to do 4+5, you'd type 4 enter 5 enter then + and the calc would show 9. entering more numbers would push the 9 onto the stack. Tricky at first but after a while you couldn't go back. No equals key. I was a civil engineer but when I started learning computer science the whole stack concept was clear.
