IO - Input Output

The IO tab is where you add/edit input and output for your calculator.

You can choose the type of input/output to use. Configure the settings by clicking the button on the added input. Here, you can make changes to the property name, label, and position of the input/output.

The following table explains the extra settings function of the input and output.

The SCRIPT tab is where you write your codes in JavaScript.

You can refer to the Cheatsheet for guidelines, but first, you need to add the input and output.

If you can't code in JavaScript, feel free to use our Script Helper and have a look at these examples.
