What's "FP"? Nothing comes to mind. As for myself, I had a Texas Instruments TI-30, I think it was, in my higher studies - it was a price revolution at the time

What's "FP"? Nothing comes to mind. As for myself, I had a Texas Instruments TI-30, I think it was, in my higher studies - it was a price revolution at the time. That was a fine simple calculator, but when somebody let me try their HP calculator a year or two later I was sold and I never looked back. RPN is just so much easier when you want to do long calculations - just begin, no need to plan things in advance.
