RPN-16C
A programmer's calculator inspired by the HP 16C Computer Scientist
If you've ever needed to do hex arithmetic, bit manipulation, or base conversion on your phone and been frustrated by the options available, this is for you.
What it does
- Full RPN (Reverse Polish Notation) calculator
- Integer arithmetic in HEX, DEC, OCT, and BIN
- Configurable word size from 1 to 64 bits
- Unsigned, one's complement, and two's complement modes
- Complete bit operations: shift, rotate, rotate through carry, AND, OR, XOR, NOT, mask, bit set/clear/test
- Float mode with configurable precision
- Keystroke programming with labels, subroutines, and loops
- Programs can be imported from text
Enhancements over the original
- Two-line display: see both X and Y registers at once
- Wider LCD: all 32 bits in binary without scrolling
- Haptic feedback on every key press
- State persistence between launches
This is a quirky calculator. It uses Reverse Polish Notation, has no equals key, and expects you to know what two's complement means. If you're looking for a simple calculator, this is not it.
