JRPN 15C

JRPN 15C: RPN calculator inspired by the HP 15C scientific calculator

Scientific calculator that simulates an HP-15C. It simulates the look and feel of the original, including the seven-segment display and the little blink you get when you enter numbers. Includes complex mathematics, matrices, numerical integration, solving the root of an equation, and statistics. Very state of the art for 1982!
