This is a RPN (Reverse Polish Notation) Calculator. It supports complex numbers and uses extended precision math for all operations. The stack depth is unlimited. In case a mistake was made, up to 10 operations can be undone.

RPN calculators work by entering the numbers on the stack first, then selecting the operation. For example to add 3 + 4, press:
