About ProgCalc
**ProgCalc Overview**
ProgCalc is a high-precision (38-digit) programmable calculator with true-decimal arithmetic, offering a Swift programming language interface for creating complex algorithms. It supports both scalar and non-scalar data types and operations. Non-scalar data types include complex numbers, quaternions, n-dimensional vectors, arrays, lists, and hierarchical tuples.
The app uses a tailored subset of the standard Swift language, optimized for numerical applications. It includes a comprehensive 38-digit scalar math library featuring well-known transcendental functions (trigonometric, hyperbolic, logarithmic, and exponential) as well as specialized functions such as arithmetic-geometric mean, arbitrary-precision rounding, modulo operations, binomial coefficients (log and normal), factorial functions (log and normal), ceiling and floor functions (toward -∞ and 0), and more.
A detailed app documentation is included, accessible via the [2nd][8] key. It provides a comprehensive guide to all calculator features, a language reference with examples and grammar, and additional resources.
**User Interface Modes**
ProgCalc offers three interactive modes, detailed in the app documentation:
- Standard infix notation (infiX, default)
- Fully editable infix notation (infiXE)
- Reverse Polish Notation (RPN)
You can switch between modes from the device’s home screen by using a pressure gesture on the app icon. On iPad devices, dedicated mode-switch keys provide a more convenient option.
**Additional Notes**
- ProgCalc is ad-free and will remain so.
- The app does not collect any information.
- The app does not rely on any third-party software.
