✨ Features

"No zero part"

No need to write a zero in decimal numbers; the calculator adds it by itself.

"Continue the calculating"

After the evaluation of the last expression,

• Press = to put the result into the input field

• Or press the operation sign (except √,㏒, ㏑) to put the result into the input field with it

"Change the operation sign"

When you put an operation sign into the input field, you can change it by pressing another.

Window size control

You can change the window size by clicking the left mouse button on the sizegrip and moving the mouse.

Inactive buttons

The buttons become inactive if their using is impossible in the current expression.

Keyboard input support

We provide keyboard support for all input buttons. You can find Keyboard bindings table in the user manual.

In-build user manual

You can always open a short version of the user manual by clicking Help or pressing the H keyboard button.

🎨 Appearance

We also provide some color themes for your better calculating experience.

📅 Plans

In the future, we are planning to add:

• Scientific mode
• Graph plotting
• Memory keys support
