C++/WinRT CalculatorEngine Project Overview

This project wraps the exprtk expression parsing library with a C++/WinRT component,
making advanced mathematical evaluation capabilities available to Windows applications.
It is designed specifically to provide calculation support for the CmdPal calculator extension.

Using exprtk

This project uses exprtk as the expression parsing and evaluation engine.

How to use exprtk in this project:

• The exprtk header file (exprtk.hpp) is included in the project source.

• You can use exprtk to parse and evaluate mathematical expressions in your C++ code. For example:

  #include "exprtk.hpp"
  exprtk::expression<double> expression;
  exprtk::parser<double> parser;
  std::string formula = "3 + 4 * 2";
  parser.compile(formula, expression);
  double result = expression.value();
  

How to update exprtk:

1. Download the latest exprtk.hpp from the official repository.
2. Replace the existing exprtk.hpp file in the project with the new version.
3. Rebuild the project to ensure compatibility and take advantage of any updates.
