It is a simple scientific calculator written in C++.
It calculates equations in RPN (Reverse Polish Notation).
Eg.
equation: 2+2*2
RPN: 2 2 2 * +
result: 6
2sin(90)+5!
RPN: 2 90 sin * 5 ! +
result: 122
arcsin(arccos(arctan(tan(cos(sin(9))))))
RPN: 9 sin cos tan arctan arccos arcsin
result: 0.027419
