Fixes #324 . Description of the changes: In an effort to support other compilers (#109), this change reworks how precompiled headers are handled. For toolchains where precompiled headers are not used, there is unnecessary compilation cost because each source file explicity includes the pch, meaning all system headers in the pch were recompiled for each translation unit. This change modifies the project's files so that each translation unit includes a minimal set of dependent headers. For MSVC users, the precompiled headers option is still enabled and the precompiled header is added to each translation unit using the compiler's Forced Includes option. The end result is that MSVC users still see the same build times, but other toolchains are free to use or not use precompiled headers. Risks introduced Given that our CI build uses MSVC, this change introduces the risk that a system header is added to the pch and the CalcManager project builds correctly, but builds could be broken for other toolsets that don't use pch. We know we want to add support for Clang in our CI build (#211). It seems reasonable to also compile without precompiled headers there so that we can regression test this setup. How changes were validated: Rebuild CalcManager project. Compile time: ~4.5s. Disable precompiled headers, keeping explicit include for pch in each source file. Compile time: ~13s. Remove explicit pch inclusion and add the appropriate headers to each translation unit to allow the project to compile. Compile time: ~8s. Re-enable pch and include it using the Forced Includes compiler option. MSVC compile time: ~4.5s. Minor changes Delete 'targetver.h'. I found this while looking around for system headers in the project. It's unused and unreferenced so let's remove it. |

Calculator
The Windows Calculator app is a modern Windows app written in C++ that ships pre-installed with Windows. The app provides standard, scientific, and programmer calculator functionality, as well as a set of converters between various units of measurement and currencies.
Calculator ships regularly with new features and bug fixes. You can get the latest version of Calculator in the Microsoft Store.
Features
- Standard Calculator functionality which offers basic operations and evaluates commands immediately as they are entered.
- Scientific Calculator functionality which offers expanded operations and evaluates commands using order of operations.
- Programmer Calculator functionality which offers common mathematical operations for developers including conversion between common bases.
- Date Calculation functionality which offers the difference between two dates, as well as the ability to add/subtract years, months and/or days to/from a given input date.
- Calculation history and memory capabilities.
- Conversion between many units of measurement.
- Currency conversion based on data retrieved from Bing.
