Description

A simple and easy-to-use calculator app that combines two calculators into one.

Calculators are displayed side by side when the screen is horizontal, and vertically when the screen is vertical.

In addition to being able to perform separate calculations with each calculator, calculation results can be also copy and paste with one touch, so you can perform other calculations during calculations, making it even more convenient to use than you might imagine.

There is also a free version with ads. Please try it first.

・When press the "→" key, the calculation result of the left calculator is entered at the end of the formula on the right calculator.
・When press the "←" key, the calculation result of the right calculator is entered at the end of the formula on the left calculator.
3. add, subtract, multiply and divide is performed.
Do multiplication and division first, then add and subtract.
4. Display the formula
The entered formula is displayed under the result, so you can easily check the operations.
5. Calculation results can be copied to iPhone’s memory
Calculation results can be pasted into other apps as text , so transcription errors will not occur.

Example of use
When you find a product for 988 yen for 3 pieces and a product for 1245 yen for 4 pieces while shopping, you can easily calculate "Which is cheaper?" And “How cheaper?"with this calculator.
1) Use the left and right calculators to find the unit price of the product (unit price = product price/number).
2) Tap the "- key" and "arrow key" on either the left or right calculator to calculate the unit price difference.

Limitations
・Answer can be calculated up to 9 digits, minimum 0.000000001.
・If you divide a value by 0, it will be ∞ correctly, but this calculator will display "0".

建议恢复横竖屏切换,竖屏正常单独计算机

计算器不需要太多功能,本身横竖屏切换是很妙的一个玩法,现在强制横屏了反而不方便,有些时候还要重新用自带计算器

谢谢你的下载。
我们目前正在考虑使计算器可以纵向使用。 请给我一些时间。

还可以更好

建议按数字时让背景变色而不是让数字变色,这样可以让用户更清楚的知道是否按下了某个数字。可以参考苹果手机自带的计算器。
