Windows Calculator: A simple yet powerful calculator that ships with Windows

Calculator

The Windows Calculator app is a modern Windows app written in C++ and 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.
• Infinite precision for basic arithmetic operations (addition, subtraction, multiplication, division) so that calculations never lose precision.

Getting started

Prerequisites:

• Your computer must be running Windows 11, build 22000 or newer.

• Install the latest version of Visual Studio (the free community edition is sufficient).

  • Install the "Universal Windows Platform Development" workload.
  • Install the optional "C++ Universal Windows Platform tools" component.
  • Install the latest Windows 11 SDK.

  

• Install the XAML Styler Visual Studio extension.

• Get the code:

  git clone https://github.com/Microsoft/calculator.git
  

• Open src\Calculator.sln in Visual Studio to build and run the Calculator app.

• For a general description of the Calculator project architecture see ApplicationArchitecture.md.

• To run the UI Tests, you need to make sure that Windows Application Driver (WinAppDriver) is installed.

Roadmap

For information regarding Windows Calculator plans and release schedule, please see the Windows Calculator Roadmap.

Graphing Mode

Adding graphing calculator functionality is on the project roadmap and we hope that this project can create a great end-user experience around graphing. To that end, the UI from the official in-box Windows Calculator is currently part of this repository, although the proprietary Microsoft-built graphing engine, which also drives graphing in Microsoft Mathematics and OneNote, is not. Community members can still be involved in the creation of the UI, however developer builds will not have graphing functionality due to the use of a mock implementation of the engine built on top of a common graphing API.

Diagnostic Data

This project collects usage data and sends it to Microsoft to help improve our products and services. Read our privacy statement to learn more. Diagnostic data is disabled in development builds by default, and can be enabled with the SEND_DIAGNOSTICS build flag.

Currency Converter

Windows Calculator includes a currency converter feature that uses mock data in developer builds. The data that Microsoft uses for the currency converter feature (e.g., in the retail version of the application) is not licensed for your use. The mock data will be clearly identifiable as it references planets instead of countries, and remains static regardless of selected inputs.

Centralize BiDirectional string code in the CalcViewModel

BiDi code is spread out - Memory panel sets BiDi in the view model, while History sets it in the CalcManager. The UnitTests also do their own thing. We should centralize the code into utility functions in the VM and then have unit tests for their functionality.

[RS5+] Update NavigationView to use DataTemplates and a template selector to generate menu in XAML rather than in code

Once our min version is RS5, we can update our app to use DataTemplates in the NavigationView. Downlevel, this is bugged and a DataTemplate with a NavigationViewItem/NavigationViewItemHeader as the top-level element will result in a double-nested item container.

Currency symbol precedence is opposite of system setting in RTL languages

In RtL languages, the currency symbol precedence is opposite of the system setting. See attached screenshots.

To repro:

1. Go to Settings > Time & Language > Region & Language > Add a language > Hebrew
2. In the languages list, set Hebrew as default.
3. Open the Run dialog (WIN + R). Enter 'intl.cpl'. The Region settings should open
4. Change the Format to Hebrew.
5. Click 'Additional Settings'.
6. Switch to the 'Currency' tab.
7. Open 'Calculator' in Hebrew.
8. Navigate to Currency Converter.
9. Observe that the currency symbol precedence is opposite of the system setting.

Programmer mode on Calculator supports unsigned values

Problem Statement
Programmers need to work with both signed and unsigned values. Calculator is currently optimized for signed values only.

Evidence or User Insights
For example, while calculator will works on INT64 numbers, if I try to paste in a UINT64 value, e.g. 18403114778001080163, it shows as invalid input. Also, currently, the Bit Flip pane only supports signed numbers (the most significant bit is the Sign bit). Unsigned number support is a gap in our programmer mode.

For example, "256" does not fit into a single byte (requires a word):

Proposal
Add support for unsigned values in programmer mode.

Goals

• Support both signed and unsigned values in programmer mode.
• Support the option to switch between working with signed and unsigned values.
• All applicable operations should adapt to signed/unsigned status.
• Ensure that terminology is consistent with standards when referring to types like QWORD, DQORD, WORD, and BYTE (these terms generally refer to the unsigned versions).

Non-Goals

• None

Low-Fidelity Concept

Requested Assignment
I'm just suggesting this idea. I don't want to implement it.

Add inking support to calculator for basic calculations/conversions or other math needs

Problem Statement

The calculator app currently supports different input mechanisms (keyboard, mouse, touch, pen), and while the app interface has been tailored in some way for for the rest of them, pen input has received less attention: the pen is treated like a regular mouse pointer with no special consideration. This is less than ideal when trying to input long numbers in a device where pen is one of the primaty input methods (e.g. Surface Studio in canvas mode, Surface Go with no keyboard attached), where many users would find easier to just write down the numbers.

Evidence or User Insights

Many Windows surfaces have benefited lately from tighter ink integration, from the new inline text input canvas to the integration of ink in apps like the Mail client, the Office suite and Microsoft To-Do. Users of pen enabled devices have come to expect more intuitive ways to interact with their computer, with the pen allowing rich ink input rather than just behaving like a simple pointer. The community response to this suggestion has been very positive suggesting that at least high-confidence users would find it a welcome addition (no pun intended).

Proposal

The proposal is to allow user to enter calculations in handwriten form, which will be recognized, parsed and calculated as any other user input.

Goals

• Allow active pen (e.g. Surface Pen) users to enter handwritten calculations, recognize them and display the result
• Understand mathematical expressions that can be expressed in one line using the same limited expression format the calculator already recognizes for pasted strings. E.g.:
  • VALID: 1+ 2 * 3
  • NOT VALID: sin(1)

Non-goals

• Provide handwriten input for touch users
  • Accuracy wouldn't be satisfactory and it would conflict with the current touch usage patterns
• Provide feature parity with the Math Input Panel
  • It would be a nice follow-up but it would require additional work on the recognition logic
• Replace the current numeric pad. It should remain available so the user is free to use the pen as a pointer if they prefer it.

Low-Fidelity Concept:

I was playing around with the code and I added support for entering expressions using ink:

It works by overlaying a InkCanvas on top of the calculation result, and leveraging the existing OnPaste method to process the recognized string.

Is this a feature you would be interested in adding? If you do I can polish it and send a PR 😊

2. In the Region settings, click 'Additional settings'.
3. Navigate to the Currency tab.
4. Change Postive symbol precedence to be on the right side.
5. Open Calculator.
6. Navigate to Currency Converter.
7. Resize to wide layout.
8. Input a large number.

Observe overlapping UI elements.

Investigate MathML rendering options

Mathematical Markup Language (MathML) is a low-level specification for mathematical and scientific content on the Web and beyond (source).

This issue tracks investigation of how Calculator might add support for displaying MathML expressions across display surfaces.

Multiple instances of app don't appear as separate processes in Task Manager

Problem Statement
Calculator supports multiple windows today, but they are all part of a single process. This means that a crash or hang in one instance brings down all instances and that it is not possible to terminate individual instances via Task Manager.

Evidence or User Insights
Terminating one instance will shut down all.

Proposal
Instead of handling multiple views of the app within a single process, we should use the new platform APIs to enable an app to be multi-instance. That will allow instances to be tracked in Task Manager, and if one instance crashes the other instances will remain alive.

Goals

• Refactor current multi-window architecture to leverage platform APIs and enable true multi-instance Calculator
• Maintain existing reliability/performance targets

Non-Goals

• None

Low-Fidelity Concept
N/A

Requested Assignment
I'm just suggesting this idea. I don't want to implement it.

Currency Endpoints: Come up with plan to change implementation to work better with new service endpoint

Addressing #77 will be enough in the short term. The end points will function as they do today, however this will only be temporary, long term we should be moving to a different set of endpoints. We will need to make some additional changes once the new end points are up and running.

Calculator Display implements Value pattern

There have been multiple issues opened against how Narrator handles the display in Calculator. The best approach would be to implement a value pattern on the display rather than using the automation name.

This deliverable should resolve the following behaviors:

• Double reading "Display is..." when the display has focus
• Announcing the "Display is" prefix every time a key is pressed
• Not announcing display value when a key press does not result in a new display value

Uneven NumberPad Margin in Converter Mode

Describe the bug
Margin around the number pad should be of equal value.

Steps To Reproduce

1. Go to any converter
2. Decrease window width until the vertical layout VisualState is triggered

** Screenshot **
Observe the following layout

Expected behavior
Padding should be equal

Recommended Solution
There are two options:

1. Decrease Right and Left margin to match the bottom (this would emulate the padding used on the main calculator interface)
2. Increase the bottom margin to match the sides.

Device and Application Information

• OS Build: 18346
• Architecture: x64
• Application Version: 10.1812.10048.0

Add the ability for users to pin Calculator on top of other windows

Problem Statement
When attempting to use Calculator with other application, such as a spreadsheet, Calculator will lose focus when you click on the other app (e.g. to scroll/copy). Users have requested the ability to pin Calculator on top of other windows to facilitate ongoing use with other apps.

Evidence or User Insights
This is our second-highest customer feedback request in Feedback Hub with some users reporting their only alternative is to pay for an app which is sticky.

Proposal
Add the ability for users to pin Calculator on top of other windows.

Goals

• Users can easily pin/unpin the Calculator window on top
• Users can easily continue with other tasks while Calculator is pinned
• Users have access to full Calculator functionality, but can always perform at least basic calculations when in the more compact view (smaller than currently allowed minimum window sizing)

Non-Goals

• Parity with the full version of the app​​ when in smallest of layout states

Low-Fidelity Concept
Here is a quick concept showing what the smallest of modes might look like. There are still several open questions to address for this layout state as well as determining the best way to enter/exit this mode:

Currency Endpoints: Update fwlinks to point to new service

The underlying service used for currency conversion will be changed in the coming months. Once the underlying service is updated, we will need to update our fwlinks to point to the new endpoints.

Calculator should not use FrameworkElement.Tag as it can be easily overwritten by internal control logic.

The use of the Tag property is bad practice and we should clean up the buttons that still use it. Tag is currently used for:

• Hamburger Button (fixed by move to NavigationView)
• About Button (fixed by move to NavigationView)
• OpenParenthesis buttons
• Programmer mode radix buttons (BIN/OCT/DEC/HEX)

Date Calculation Does Not Factor In Leap Year

Describe the bug
The next occurring leap year is next year 2020! The actual Leap Day is Saturday Feburary 29th, 2020. In a recent round of tests with the Date Calculation I found that when adding days past the next leap day the calculation acted as if that day never existed and didn't account for the fact there is an extra day in the year. I set up the case with Today's date February 20,2019 and added 1 year, 0 months and 6 days. The answer came to be A February 26, 2020 just 3 days before Leap Day. I then added an extra year to the equation and got February 26, 2021, which normally that is fine but with leap year it would actually be February 25th, 2021 because of the extra day.

Steps To Reproduce

1. Launch the Calculator app build 10.1812.10048.0.
2. Navigate to Date Calculation.
3. From the drop down field select Add or subtract days.
4. For the from date enter February 20,2019
5. Check the bubble Add
6. Enter 1 Year, 0 Months, 6 Days.
7. Take Note of the date Wednesday, February 26,2020 (3 days before Leap Day)
8. Change Years field from 1 to 2.
9. Observe new date Friday, February 26, 2021.

Expected behavior
Leap years are taken into account for date calculations.

Device and Application Information (please complete the following information):

• OS Build Number:
• Architecture: x64
• Application Version Number: 10.1812.10048.0

Additional context
What is also interesting here is that normally the days of the week move forward one day from the previous, except in the case of leap year and then it is two for any date past Leap Day. So looking at this the days of the week has been adjusted for leap year, but the calendar date was not.

Support for arrows keys for +, -, *, / for compact keyboard

Some third party calculator support the arrow Keys for typing the four principal operators in compact keyboards. Now it seems like these Keys are unused, it would be useful to use them for this
Regards,
Manuele

Does not support paste of monetary values

When pasting input that contains a prefix currency symbol (e.g., $5), the display shows "Invalid input". We should not treat this as invalid input, but instead trim away prefix currency symbols and treat them as numerical values.

Calendar in the calculator appears outside the window

In Date Calculator, you can select the date from the calendar, but the display is bugged and the calendar will be shown outside of the window.

Found in OS build: 10.0.17763.292.amd64fre.rs5_release.180914-1434
Original bug has no Calculator version information.

Length conversion should use Feet + Inches instead of Feet with decimal point

Problem Statement
Today, length converter shows decimal values for feet, while in practice, feet + inches are oftentimes used.

Evidence or User Insights
Observation of current behavior and customary use in U.S. and U.K. Details on foot (unit).

Proposal
When converting to feet, in addition to showing the decimal conversion, also include "feet + inches", which is more commonly used when working in this unit. For example, when converting 230cm, Calculator shows 7.545932 feet. It would be more useful if it would also show 7' 6.55" (feet with inches).

Possibly dependent on #379.

Goals

• Additionally show the "feet and inches" conversion when working with feet in length converter.

Non-Goals

• Remove decimal representation of values in feet

Low-Fidelity Concept

Requested Assignment
I'm just suggesting this idea. I don't want to implement it.

Adopt C++ standard types across codebase

Calculator currently uses windows-specific types in some places, such as UINT. We should adopt the C++ standard types in their place.

Calculator should use constexpr when defining static const strings

Many strings in Calculator should not be modified and so we declare them 'static const'. This is fine for ensuring compiler-enforced const-ness, but a downside to this approach is that the strings aren't created until runtime. We can improve this by marking the strings with 'constexpr'. This will tell the compiler to bake the strings into the binary itself, which results in less overhead.

Document Calculator telemetry events

A team member will update this issue with more details soon.

Cleanup the templates for custom controls in Calculator

Calculator has a bunch of inefficiencies in its styles that hurt performance and maintainability:

• Unnecessary nested UI containers.
• Use of LyaoutUpdated events.
• Unnecessary focus visuals.

compact overlay for calculator in tablet mode

if the calculator has compact over lay i can use it like an actual calculator in tablet mode. It will be just like the desktop and i can use it instead of having to go into the app separately.

Update calc engine to remove existence of negative 0

The current calc engine has many cases that result in a calculation of negative 0. While there are a couple spots where this is checked and resolved (2, to be exact), this should be improved to prevent cases like "not(1-1) = -1".

Update Calculator engine’s use of smart pointers

The Calculator engine allocates and frees its own memory which leads to issues such as double-frees that are hard to investigate. We should clean this code and switch to modern constructs such as smart_ptrs to eliminate these issues.

Currency Converter: Update country name from "Macedonia, FYRO" to "North Macedonia"

The country name Macedonia has been changed to North Macedonia. Currency Converter retrieves the country name from the Bing currency web service, so we need to work with Bing to update what the service returns from "Macedonia, FYRO - Denar" to "North Macedonia - Denar".

Programmer Mode should support setting the radix based on pasted values

Problem Statement
Calculator currently supports pasting in prefixed/suffixed values in programmer mode if the value is considered valid for the current radix (hex/dec/bin/oct).

Evidence or User Insights
This is a small quality-of-life improvement when using programmer mode.

Proposal
Upon paste in programmer mode, if invalid input is detected, attempt to detect if the value is valid in a radix other than the current one, and if so, automatically switch to that radix and accept pasted value.

Prefixes

• Pasted input with prefixes always automatically change to specified radix (e.g., "0b" = binary; "0x" = hex, etc.)

Suffixes

• If pasted input is valid in currently selected radix, prefer to remain in selected radix (e.g., pasting "10b" while in hex results in remaining in hex with "10B").
• If pasted input is invalid in currently selected radix and is valid in exactly one other radix, automatically change to specified radix (e.g., pasting "10F" in decimal is invalid and is only valid as hex input, so switch to hex).
• If pasted input is invalid in currently selected radix and is valid in more than one other radix, do not change radix and display "Cannot determine radix" (e.g., pasting "10b" in decimal is invalid, but is valid input for both binary ('b' suffix) and hex ("10B" is valid hex).
• If pasted input is invalid across radices, maintain current behavior and display "Invalid input".

Goals

• Minimize instances we display "Invalid Input" by automatically switching radix when we can do so confidently.

Non-Goals

• Add support for additional radix prefixes/suffixes.

Low-Fidelity Concept
N/A (use existing UI; just switch radix when appropriate)

Requested Assignment
I'm just suggesting this idea. I don't want to implement it.

Investigate migration of calc engine to BigInteger/BigRational

There are existing BigInteger/BigRational libraries. If there is one at parity with the existing Calculator engine, we can investigate replacing the older engine code.

Update Calc x:Name values to begin with uppercase

Any and all occurrences of x:Name should use Pascal-case. Right now, it is inconsistent between views. The reasoning is that x:Name converts the object to be accessible as a property of the current view and properties should be Pascal-cased. I think this issue is easily fixed with a regex + replace.
