About Calculator Plus v2
Calculator Plus is a standard and scientific calculator that has simplicity at its core, while not compromising on functionality. Even with its simple user interface inspired by the built-in Calculator app on iOS, it offers much, much more - and with no ads!
With full expression and live answer preview, be faster than ever at calculating, see exactly what you typed. Understand your answers by displaying them in exact form, scientific notation, fractions and more. Catch the exact errors with helpful syntax errors, with beautiful animations to complement your calculations. The full scientific calculator is also present in the portrait layout, so now you can calculate scientific operations away one-handed on your phones.
That's not all! If you're on a Mac, or have a hardware keyboard connected to your iPad or iPhone, simply type your math expressions normally and it will be registered - including every scientific operation listed. Clipboard support not only allows you to copy your calculations for others to see, it also gives you the ability to instantly take any expression from anywhere and paste into the app.
Bonus features: With voice dictation input optimised to understand mathematical expressions, calculate any expression quickly and efficiently. On an iPad, your Apple Pencil works with iPadOS 14's Scribble to allow for direct handwritten inputs - no dedicated handwriting panel, just write anywhere on the calculator! All these are powered by Apple's own software, so be rest assured that no data tracking is done by the app itself.
Download Calculator Plus to experience it for yourself!

- Custom Scientific Typing Mode: Append, Substitute or a hybrid of both when using on-screen buttons.
- Full Hardware Keyboard input support (including scientific operations!)
- Apple Pencil Scribble support on iPadOS 14+ in English.
- Basic Voice Dictation input support in English.
- iPadOS SlideOver, Split View and Stage Manager multitasking support.
- Satisfying clicks with haptic feedback on modern iPhones.

2.2.6
Oct 6, 2023
- Fixed a crash on iPadOS 17 when attempting to use Apple Pencil Scribble.
- Fixed an issue where calculations resulting in 0 will display an arbitrary tiny value instead (like 1e-14).
- Addition and subtraction operations are now strictly limited to approximately 14-15 digits of precision. Hence, 1e14-1.01 will be computed as 1e14-1 instead. Note that the app never displays answers in more than 12 digits of precision anyway - this is an internal limit.

- Minor in-app info updates.
- Minor in-app info updates.
2.2.4
Jan 11, 2023
- Fixed an interpretation issue with negative number parsing using the scientific notation (e.g., 1E-2) not being of highest priority.
- Ambiguous operations now automatically include extra brackets to indicate the order the calculator evaluated the expression.
- Warnings regarding your expression, if any, will now pop up even if you did not press "=" to calculate the answer.

- Warnings regarding your expression, if any, will now pop up even if you did not press "=" to calculate the answer.
2.2.3
Dec 27, 2022
- Fixed: Percentage Change Notation auto-correction did not work when using the "ans" keyword for prior answers.
2.2.2
Dec 21, 2022
- Improved: If your region or number format settings uses commas (,) as decimal separators and thousands separators are set to a space or turned off (like 1 234 567,89), the app will produce unexpected output when you do not input numbers matching your current format. Specifically, numbers with periods (.) as decimal separators (like 1.2345) will be interpreted incorrectly. In this update, with this exact scenario, the numbers will be converted to your local format (so 1.23 -> 1,23).
2.2.1
Dec 19, 2022
- Fixed: Non-Standard Percentage Change Notation may perform unnecessary corrections on already standard notation.
- Fixed: Some switches in Settings do not toggle the correct setting.
- Fixed: Apple Watch Math Evaluation Overrides may have certain rules that do not appear to be togglable.
- Improved: Arbitrary physical keyboard layouts now work correctly on at least iOS/iPadOS 13.4 and macOS 10.15.4 and newer.
- Improved: The "E" operator, where "xEy" = "x*10^y" for scientific notations, has been updated to be a universal operator (instead of only numbers), which can be used with bracketed parameters and chained. When chaining, it is evaluated left to right (so 3E2E2 = 3E4).

Apr 10, 2022
This update includes some important fixes for legacy devices:
- Attempts to fix a crash on a small portion of devices running iOS 9-12.
- Fixed an issue where small iPhone sizes won't have the landscape scientific calculator show up. This occurs in small legacy devices like the iPhone 4S and 5 series, plus the first gen iPhone SE.
Additionally:
- App logs may be retrieved on macOS if additional details are needed for customer support, with your consent.
Note: Version 2.1.x are the last versions of the app to officially support devices as old as iOS 9. Version 2.2 and later may require a newer iOS or iPadOS version to function. For macOS and watchOS, the OS requirements are not affected.

Mar 10, 2022
Hope you'll like this new update with a large selection of new features and fixes!
- Added a cursor to allow adjusting any part of your typed expression. No more clearing and retyping!
- Added History Tape. Currently, history will only be saved for the session and won't persist across app restarts.
- Added calculation warnings. In case of ambiguous interpretations or problems, this will allow you to better understand the results obtained.
- Decimal separator button "." should now follow your local region preferences.
- Blank space is now automatically used as the thousands separator in answers.
- Added option to 'Float on Top' of other apps in macOS.
- Added Menu Bar items on macOS.
- EE button now outputs 'E' instead of 'x10^' which allows them to be treated separately and correctly given higher priority (so operations like 6E5 ÷ 2E4 = 3E1 will now be correct)
- Resolved rounding errors causing cascading inaccuracies with trigonometry functions, especially for terminal values like tan(90° + 2πk) and cos(90° + 2πk) up till approximately 1E12°.
- The 'x!' operation now computes the gamma function + 1 instead of just an integer factorial calculation, and thus will now work with negative and non-integer numbers.
- Implicit multiplication and fraction division have updated priorities. In case of ambiguity, new calculation warnings will also warn you of any potential differences in interpretations.
- Negative numbers in an exponent "chain" previously had unconventional parsing, which is now resolved to interpret with the order of operations literally. It is still recommended to avoid ambiguous syntax by using brackets to prevent confusion.
- Resolves a bug with the macOS calculation display being clipped offscreen.
- Resolved auto-formatting issues for negative numbers.
- Patched a bug where dictation may not function.
- Copy/Paste functionality is now compatible with iPadOS 3-finger pinch gestures.
