* Replacing CalculatorVector usage with std::vector
Assumptions made here are that memory allocations
are not recoverable. If it can be proved that an index
will be in range, then the indexing operation is used.
If not (without manual checks) the std::vector::at function
is used to throw an exception in case of a programmer bug.
* Changes based on PR feedback
Using auto& in CalculatorCollector::UpdateHistoryExpression
so the token.first value is properly updated.
Using range for loop to GenerateExpressions.
Setting isEditable directly to the result of boolean expression.
Using token.second directly instead of creating a
separate tokenCommandIndex variable.
* Fixing issue with generating expressions strings.
A space should not be added before the first item.
### Description of the changes:
**1) Do not set units to default values if they already have valid values**
This fixes the actual issue. `UnitConverter::InitializeSelectedUnits()` ( this function resets all units to their default units if available for the current category ) gets called after `UnitConverterViewModel::RestoreUserPreferences()` ( this function restores user preferences ).
So Calculator has been restoring saved values, and then overriding the restored values with default values.
I modified `InitializeSelectedUnits()` so that we only initialize units only when they are not already set to valid units for the current category.
**2) Removed `m_isFirstTime`**
I noticed that we are calling `RestoreUserPreferences()` twice when Calculator starts up, and the function is restoring the same value both times
The below happens when Calculator starts up
1) On startup, in `UnitConverterViewModel::InitializeView()`, `RestoreUserPreferences()` is called.
2) `RestoreUserPreferences()` in turn triggers `OnUnitChanged()`
3) During the first call to `OnUnitChanged()`, m_IsFirstTime is `True`, so we call `RestoreUserPreferences()` again while also setting `m_IsFirstTime` to `False`.
4) `RestoreUserPreference()` again triggers `OnUnitChanged()`
5) During the second call to `OnUnitChanged()`, m_IsFirstTime is `False`, so we call `SaveUserPreferences()`
I think we should only call `SaveUserPreferences()` inside `OnUnitChanged()` since we already restored user preferences during view initialization. I can't really think of a reason to restore units after view has been initialized. This led me to just delete `m_isFirstTime`.
### How changes were validated:
Manually tested that units and the current category are properly selected when you quit and start Calculator.
## Fixes#445.
* precisely calculates the number of digits of the source and compute the number of significant digits of the result based on that.
* fix unit test
* Fix warning C4267
* Optimize how we calculate the number of digits in the integer part and don't trim the value when used by the currency converter
* modify GetNumberSignificantDigits
* fix CI error
* Access to wstring::npos from static calls
* Move UnitConverter static methods related to number to NumberFormattingUtils
* rename namespace
* Add comment and fix typo
* Move standard headers
Having an extra integer variable to hold onto an i or i-1 value is inefficient, for "if (m_token.at(i) != chZero)", the code under "fDigitsFound" will always run, so it makes sense to put the fDigitsFound code under the if statement, which can return from the function entirely instead of breaking.
### How changes were validated:
- Manual Testing verified the code having identical behavior as before, with no side effects.
`mulnum` et al. are declared `extern` in `ratpak.h`, which conflicts
with the `__inline` used with them. Additionally, most similar functions
don't have such keyword applied to them.
This is extract from #211 that enables compilation with GCC. With #211
now in the state of bitrot, I would rather try approaching it in smaller
steps that can be hopefully merged quicker, even if it does not provide
full support for all the features #211 provided.
This will _compile_ correctly with my (@janisozaur) GCC, but clang is
more picky about flexible array members and refuses to compile it yet.
I will extract remaining parts of #211 in future PRs.
I marked @fwcd as author, as he did most of the work in #211.

This PR fixes code style for the project files.
The Problem
Different files in the project use different code style. That is not consistent and leads to harder maintenance of the project.
Description of the changes:
Have investigated and determined the most used code style across the given codebase
Have configured IDE and applied code style to all project files.
Have crafted clang-formatter config.
see https://clang.llvm.org/docs/ClangFormat.htmlhttps://clang.llvm.org/docs/ClangFormatStyleOptions.html
Some cases were fixed manually
How changes were validated:
manual/ad-hoc testing, automated testing
All tests pass as before because these are only code style changes.
Additional
Please review, and let me know if I have any mistake in the code style. In case of any mistake, I will change the configuration and re-apply it to the project.
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.
Fixes#382
Description of the changes:
Add Pyeong as an Area conversion unit.
Pyeong shows up only if the user's current region is Korea ( i.e. region is either KP or KR ).
Added Korean translation for Pyeong (평). For other locales, we default to English ( Pyeong ).
How changes were validated:
Manually tested the below
For non-Korean regions, Pyeong does not show up.
Korean region with Korean locale => Pyeong shows up and Pyeong is correctly translated.
pyeong_Korean
Korean region with English locale => Pyeong shows up and Pyeong is in English.
pyeong_English
Korean region with simplified Chinese locale => Pyeong shows up and Pyeong is in English.

## Fixes#111
> The modulo operator on this calculator gives the result that is different to the most used calculators.
The current `modrate` function is the equivalent of rem(...)/remainder(...), not mod(...)/modulo(...) available in some popular Math apps.
### Description of the changes:
- rename `modrate` in `remrate` to be more accurate.
- add `modrate`, calculating modulo similarly to Matlab, Bing, Google calculator, Maxima, Wolfram Alpha and Microsoft Excel
- Add `RationalMath::Mod` using `modrate` as an alternative to `Rational::operator%` using `remrate`
- Add a helper `SIGN` to retrieve the sign of a `Rational`.
- modify `CalcEngine` to use `modrate` in Normal and Scientific mode and `remrate` in Programmer mode.
### How changes were validated:
- manually and unit tests added
Fixes#260
Description of the changes:
prevent UnitConverterViewModel to reset values when users click on update rates.
recompute UnitConverter's caches (m_ratioMap and m_categoryToUnits) once rates are updated (but check first if the user did/didn't change the category)
How changes were validated:
Manually tested with fake currency rates (HTTP responses modified on the fly via FiddlerCore)
Verified that it works no matter the selected field (From or To)
Verified that the currencies selected are kept after a refresh
Description of the changes:
Currently Calculator handles strings by defining integers for each type of function that can be performed, this integer will eventually correspond with an index in s_engineStrings which holds the corresponding display string for each function. Some functions such as Sin can have multiple strings (degrees, rads, grads, inverse). Functions like Sin are mapped to another array called "rgUfne" where a new integer is given depending on the output string which will then be given to s_engineStrings. The new integer returned by the "rgUfne" array runs the risk of overlapping with any new functions that may be added in CCommand.h. Furthermore, it is expected that the strings in s_engineStrings and rgUfne are defined in a particular order (not necessarily sequential), otherwise the logic will break. This makes adding new strings for new functions confusing and difficult, since a lot of the logic is not clearly defined.
This PR attempts to make this a bit simpler by changing the s_engineStrings and rgUfne arrays to be unordered_maps instead of arrays. For s_engineStrings the keys will now be strings, allowing the existing logic for indexing to be used by simply converting the number into a string to access the value. This will also allow us to create keys in the future that are not limited to integers but to strings that hold more meaning.
The rgUfne array will also be updated to be a map that will take in an integer and give you the corresponding string that can be passed to s_engineStrings. The UFNE object in the rgUfne array will also be updated to hold all the possible string keys for a function, instead of indexing them on other numbers that may overlap with existing definitions.
Now to add a new string for a new IDC_FOO function, we would just need to add the "FooString" resource keys to the g_sids array and use the updated rgUfne map to link the IDC_FOO value to the corresponding "FooString" resource key. This way the resource key can be a meaningful string, and not an integer that must be in any particular order.
How changes were validated:
Tested each function manually in standard, scientific, and programmer modes.
The conditional m_precedenceOpCount >= 0 was always true because m_precendenceOpCount is an unsigned type. Update the conditional to simply be true and rely on a break statement in the loop. Although this member variable used to be a signed type, in practice, the value was never less than 0.

I have no idea if it is required to be `sealed`, I have seen no `^`
operator which makes me think it could be a regular C++ code, barring
the concurrency stuff.
