Calculator Plus v2

- Fixed keyboard shortcuts on the numpad - the Enter and Clear/NumLock keys now correctly trigger "=" and "AC" respectively. - When an answer is computed, "Copy Full Calculation" now has a separate keyboard shortcut, while the usual CMD+C copy keyboard shortcut now invokes "Copy Answer". - Updated watchOS app calculator interface layout and complications compatibility. Note: Version 2.1.x are the last versions of the app to officially support 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.

- New "⁺⁄₋" button to invert the number before the cursor to its negative. - New number format options. Change your preferred decimal and thousands separator, and the function argument separator. - New Math Evaluation Overrides which allow you to use non-standard notations or evaluation orders. Notable options include: - Automatically replace non-standard percentage change "x+y%" with the standard notation "x(100+y)%". - Change evaluation priority of implicit multiplication and fractions. - New options to choose whether the app's expression and answer formatting is copied when copying your calculation. - Evaluation priority for implicit multiplication is now by default the same as standard multiplication. - You can now hold down the Command or Option key to see a hint on how to type all functions with a physical keyboard. - The forward delete key (also fn+delete) now works correctly on hardware keyboards. - Hardware keyboard input is now improved for iPadOS 13.4+ and macOS. - You can now use keyboard tab navigation to navigate the History Tape and Settings pages on iPadOS 15+ and macOS. - Reduced minimum height for portrait scientific calculator to allow better use in Stage Manager on iPadOS. - Support for the latest iPhone and Apple Watch models. - Dropped support for iOS 9 and iOS 10.

- 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).

- 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).

- Fixed: Percentage Change Notation auto-correction did not work when using the "ans" keyword for prior answers.

- 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.

- Fixed a crash when pressing +/- right after pressing ). - Minor in-app info updates.

- 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.

- Fixed: The app button layout was squished on watchOS 10. This is now resolved. - Fixed: Using the arrow keys to navigate and edit your expression after an answer has been computed may cause your entire expression to be lost. This will no longer happen. - New: Dictation on iOS, iPadOS and macOS now support continuous voice input. Simply say "equals" to get the result, then continue speaking what you want to calculate next. Hint: Use "answer" in your speech to reuse a result from a previous calculation. - Improved: The watchOS app now has colored backgrounds and vertically scrollable pages on watchOS 10 to better match system conventions. - Improved: The watchOS app now has a new organization of pages with separate pages for settings. - Improved: The macOS app now has a translucent blurred window on macOS 11 and later to better match system conventions.

- Fixed: A critical bug may cause tiny numbers with a magnitude lower than 1E-14 to be treated as 0 during addition and subtraction. - New: The thousands separator is now also displayed for numbers in the input expression (previous versions only use them in the answer). - New: Inputs are now instantly autocorrected and/or disambiguated as you type (previous versions only show them when pressing '='). Some rules may be configurable in Math Evaluation Overrides. - Improved: Percentage change via non-standard math notation of "a ± b%" is now enabled by default, utilizing instant autocorrect to provide visual feedback. - Improved: The background color is now of higher contrast and lower translucency. - New: Updated icon to match iOS 18 and iPadOS 18.

- Fixed: A critical bug may cause tiny numbers with a magnitude lower than 1E-14 to be treated as 0 during addition and subtraction. - Fixed: The app may crash when the answer of the calculation is exactly 2^63. - Fixed: The Apple Watch app settings and help pages may not correctly open. - New: The thousands separator is now also displayed for numbers in the input expression (previous versions only use them in the answer). - New: Inputs are now instantly autocorrected and/or disambiguated as you type (previous versions only show them when pressing '='). Some rules may be configurable in Math Evaluation Overrides. - New: Permutations (nPr) and Combinations (nCr) are now available. - Improved: Percentage change via non-standard math notation of "a ± b%" is now enabled by default, utilizing instant autocorrect to provide visual feedback. - Improved: The background color is now of higher contrast and lower translucency. - New: Updated icon to match iOS 18 and iPadOS 18. - New: On iOS and iPadOS, you may now change the app icon between any variants used since version 2.
