Calccis is a simple reverse polish notation (RPN) calculator app for iOS. It supports basic arithmetic, trigonometrical, logarithm and exponent calculations. Degrees and radians can be used for trigonometrical functions. Starting from version 1.0.2, Calccis supports calculations with complex numbers, too.
Calccis uses the usual double-precision numbers for calculations, which makes small inaccuracies in calculation results quite common (e.g., 0.1 + 0.2 != 0.3).
Calccis does not copy or mimic any existing physical calculators. However, the operation of the stack has been influenced by how the stack works in the 1990s Hewlett-Packard HP-48 family of calculators.
The source code of Calccis is available in a Git repository at https://github.com/jaittola/calculatrice. If you encounter problems with the application, please file an issue at https://github.com/jaittola/calculatrice/issues.
