App: Calculator Plus v2
Developer: Wern Jie Lim
Genres: Utilities, Productivity

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.

Release notes:
- 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.
