Scientific Calculator +DB

带有内置数据库的科学计算器存储结果或公式。

***THIS APP DOES NOT ACCESS THE INTERNET***

It just needs the permission for technical reasons, for the database.

It does not require, nor use, internet access at any point.

A scientific calculator with a built-in database to store results ,formulas, or constants with descriptions.

A graphical interface, for both the calculator view, as well as the database view.

Insert anything from the database directly into the calculator, at the caret position.

Features a tidy database (SQLite) with folders, and subfolders, and a search option, of course.

This app is still in development.

And will continue to improve for a while.

In the future, solving equations and function plotting is planned.

For now, however, take a look at the following list of upcoming features and changes.

The list:

Add navigation buttons for hard to hit carets.

Fix caret touch event.

Replace zoom controls with pinch gesture.

Store values as symbols until presentation. (current is double)

Refactor operator application.

Assign symbols to database items, allowing to store/recall symbol, instead of value ( Pi, instead of 3.1459...)

Calculation history option

Save settings to prefs.

Center camera on caret on insert.

Alter presentation to fix the sprites' quality.

Add highlight to empty expression.

Update this list, and add more stuff :)
