# PiCalc-Win 
Experiment in making a GUI Pi Calculator app from scratch in C++ using native Win32 API.
Compatible with Windows XP and up.
Uses:
- Selectable algorithm for computing π (Chudnovsky by default)
- C++ Threading
- SIMD
- Console Window for logging
- GDI rendering (LOL)
## Building
– Building requires Visual Studio 2017/2019/2022, the C++ workload, and WinSDK 19041 or higher installed.
For Windows XP Support, use the PiCalc-WinXP.sln, and install the v141_xp platform as per [Here](https://learn.microsoft.com/en-us/cpp/build/configuring-programs-for-windows-xp).
