## Overview

Caluctor is a small WPF calculator. A user enters numbers and selects basic or scientific operations in the main window; the window evaluates operations and updates the display. It also supports saved-number memory. The sampled code shows the main window discovering and invoking .NET Math and MathHelper methods, and creating memory panels. The excerpts do not show the XAML layout or application startup wiring, so those links are omitted.

Main entry points: [`MainWindow.xaml.cs`](https://github.com/thefocusman/caluctor/blob/master/MainWindow.xaml.cs) (Calculator workflow), [`MainWindow.xaml`](https://github.com/thefocusman/caluctor/blob/master/MainWindow.xaml) (Calculator window), [`MathHelper.cs`](https://github.com/thefocusman/caluctor/blob/master/MathHelper.cs) (Scientific operations), [`OutputFormatAttribute.cs`](https://github.com/thefocusman/caluctor/blob/master/OutputFormatAttribute.cs) (Operation formatting)
